We use dts from Linux and we don't have specific maintainer for these (atleast no need).

I think Kever has merged the LPDDR4 series, and it's already made its way into the mainline u-boot master branch. https://gitlab.denx.de/u-boot/u-boot/commit/852f6ddd76fad2d5adef3f7e3a75d0065c68db3b and its ancestors are the v3 series Jagan posted to the list.

I'll update the patches and send them soon. I'll make sure I test your specific patch when you post it, but I can already confirm that u-boot.git master happily boots a Khadas Edge board. I just added the unmodified Edge device tree from mainline Linux into arch/arm/dts/, created the u-boot fixup .dtsi and\x05 defconfig with sed 's/rock-pi-4/khadas-edge/g' configs/rock-pi-4-rk3399_defconfig \ >configs/khadas-edge-rk3399_defconfig cp arch/arm/dts/rk3399-{rock-pi-4,khadas-edge}-u-boot.dtsi make khadas-edge-rk3399_defconfig then built u-boot with an rk3399 bl31.elf from master of arm-trusted-firmware.git. It boots TPL -> SPL -> U-Boot proper -> Linux just fine without any external idbloader.bin or standalone trusted firmware - faster and much less noisy!

* [U-Boot] [PATCH v2] arm64: dts: rockchip: Add support for Khadas Edge/Edge-V/Captain boards 2019-06-17 7:24 ` [U-Boot] " xieqinick at gmail.com (?) @ 2019-06-18 7:21 ` Kever Yang -1 siblings, 0 replies; 43+ messages in thread From: Kever Yang @ 2019-06-18 7:21 UTC (permalink / raw) To: u-boot Hi Nick, Thanks for your patches, please help to split dts and config into different patches, and also one patch for one board instead of 3 boards. One defconfig for board, while Khadas Captain is the carrier board for Khadas Edge, the caption and the Edge should able to share one defconfig in U-Boot?

I don't see DRAM configuration here so it seems that it relies on the non-free rockchip loader. If that is the case, could you please indicate that in the commit message? To maintainers: please do not merge this series before DRAM init and SPL support is available for these boards. It seems that other RK3399 boards were merged without SPL support and sofar, I have the feeling that nobody cared to explain how we got into this broken situation. Please don't merge any more such board.

* [U-Boot] [PATCH v2] arm64: dts: rockchip: Add support for Khadas Edge/Edge-V/Captain boards @ 2019-06-18 8:25 ` Paul Kocialkowski 0 siblings, 0 replies; 43+ messages in thread From: Paul Kocialkowski @ 2019-06-18 8:25 UTC (permalink / raw) To: u-boot Hi, On Mon, 2019-06-17 at 15:24 +0800, xieqinick at gmail.com wrote: > From: Nick Xie <nick@khadas.com> Was this tested with SPL support? I don't see DRAM configuration here so it seems that it relies on the non-free rockchip loader. If that is the case, could you please indicate that in the commit message? To maintainers: please do not merge this series before DRAM init and SPL support is available for these boards. It seems that other RK3399 boards were merged without SPL support and sofar, I have the feeling that nobody cared to explain how we got into this broken situation. Please don't merge any more such board.

Here is a quote from Philipp Tomsich on the thread we discussed this: " On some boards, there will be no TPL and only a SPL stage that will initialise DRAM (as the move to having TPL on the RK3399 is optional). I agree with Paul that the DRAM init should be part of U-Boot whenever we add new boards and make an open DRAM init a prerequisite. " So even if I frequently confuse SPL and TPL, it doesn't change the fact that no board should be merged without proper DRAM init. Please stop pushing for merging these boards. I'm not sure what we should do about the boards that were merged already without DRAM init, but maybe they should be reverted.

I don't think we have to have full DRAM init source code for each board before we can merge it, I believe most of the board on U-Boot mainline need to removed due to this rule. There are so many boards from different vendor need a binary loader before U-Boot, and I can see only very few drivers for dram at driver/ram/, and I believe rockchip is already the most open vendor on this area. I won't use this rule to stop developers contribute there source code, for a board support, we only need the board to have the full documentation about how to setup and boot with upstream U-Boot. and I think the most of people cares more about features in U-Boot proper. Everything before U-Boot proper, you can use TPL/SPL or alternative to use binary from vendor, as you can see all over the U-Boot mainline now, although we encourage people to use full open source TPL/SPL. Specifically for U-Boot Rockchip platform, I would like people to support not only U-Boot proper, but also for full SPL(ATF, OP-TEE support, itb image and other features) support. And for DRAM init, - if this belongs to SPL for this board, you must implement it or else SPL won't work; - if this does not belong to SPL for this board, you need implement full function SPL; and you can either to have full function TPL with DRAM init(which is prefered) or alternatively use binary loader from vendor. I'm not sure if you have write a new dram driver for a board, but I know even the board vendor may not have the capability to write the DRAM driver, so this should not stop developers contribute to all other 99% features on U-Boot.

I don't think we have to have full DRAM init source code for each board before we can merge it, I believe most of the board on U-Boot mainline need to removed due to this rule. There are so many boards from different vendor need a binary loader before U-Boot, and I can see only very few drivers for dram at driver/ram/, and I believe rockchip is already the most open vendor on this area.

Well, I am not talking about full DRAM init source code as in dynamic link training. I am talking about having at least static DRAM register configuration values, which is present for a good number of rockchip boards. Of course, it would be best if Rockchip would consider releasing this source code, which would be the easiest and friendliest solution towards the community here. Are there internal discussions ongoing about this?

This is not really a technical argument here, more of a policy argument that ensures we have full free software support for the boards we support, and not only half-cooked support (that will most likely never be completed as soon as something that works gets merged). So it is a strategical decision, not a strictly pragmatic one. I think reverting patches adding support for boards with no DRAM configuration at all would send a message in the right direction here. > I'm not sure if you have write a new dram driver for a board, but I know > even the board vendor may not have the capability to write the DRAM > driver, so this should not stop developers contribute to all other 99% > features on U-Boot. What they can do is run the non-free blob, dump the registers afterwards and then use that in the DRAM configuration dtsi. Perhaps one could write up a tool to ease the process if they think the process is too much for a regular bringup. Most of the time, the DRAM chips are soldered so the calibrated values have about no reason to change over time and can just be kept as-is. What do you think?

A significant number of u_boot targets rely on closed source components. In the particular case of RK3399 the situation is better than for other boards since you can combine the binary loader from the vendor with mainline U-Boot and mainline ATF to create a firmware where (as far as we can tell) no closed soure component remains active after U-Boot and ATF take over control. > I think reverting patches adding support for boards with no DRAM > configuration at all would send a message in the right direction here. Frankly, I don't think that would help. It would just drive more people to the vendor U-Boot that has more bugs and includes a vendor supplied ATF binary. > > I'm not sure if you have write a new dram driver for a board, but I know > > even the board vendor may not have the capability to write the DRAM > > driver, so this should not stop developers contribute to all other 99% > > features on U-Boot. > > What they can do is run the non-free blob, dump the registers > afterwards and then use that in the DRAM configuration dtsi.

Hopefully the pending diff to add support for other DRAM types beyond those that are already supported would make bring us a long way in that direction. Maybe one of the existing timings will already work for the boards that are being discussed here. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot ^ permalink raw reply [flat|nested] 43+ messages in thread

Hopefully the pending diff to add support for other DRAM types beyond those that are already supported would make bring us a long way in that direction.

As a developer, I agree on this, but as a maintainer, I know too many developers not able to do it and what most of developers need is other features in U-Boot or SPL, and I would like the U-Boot mainline is more active with more and more developers. So I'm afraid I agree with Mark at this time for the policy. If all the other SoC platforms can have the same rule for DRAM init driver is a mandatory instead of option, eg. brcom, qcom, mtk, omap, tegra, stm, imx, aml, and all others, then I would very happy to follow the rule. Rockchip is open for open source the DRAM driver, you have to know this is the decision by the vendor, but not any of developers. On rockchip platform, developers no need to concern about the DRAM driver(which is pretty hard for most developers) because rockchip already contribute it. For the time now, I know there will be full DRAM driver for rockchip SoC, so the SoC/board support could be step by step: U-Boot proper -> U-Boot + SPL(no DRAM init) ->U-Boot + SPL + TPL. As you can see the rockchip LPDDR4 driver send by Jagan, has 99 patches in V2, you can't use static register configuration to do this, and maybe you can't have a workable version if rockchip don't release it, but I don't think it's correct to make all those boards with lpddr4 float outside the mainline support because many developers are using the boards, they can only use vendor branch if the board not support by mainline. So I think merge those patches already make board work on mainline U-Boot is pretty important for open source community. Thanks, - Kever > Frankly, I don't think that would help.

I thought that LPDDR4 works the same as other types of DRAM where we have a dtsi array with timings configuration. Of course, some more registers need to be set up, but we already have support for that or it's quite close (for LPDDR4). > > > which is present for a good number of rockchip > > > boards. > > No, there is no rockchip board only have static DRAM register > configuration values, that maybe happens in other vendor. I was implying that, as far as I know, it is the case for DRAM timings on Rockchip as well as most of the platforms that I know of. In the end, any code handling DRAM will end up writing timings to the controller's registers. If the DRAM is part of the PCB and doesn't change/move, then the timings don't change in particular. Is there something specific about Rockchip that makes it require different DRAM timings at each boot? > > > Of course, it would be best if Rockchip would consider releasing this > > > source code, > > Rockchip already release all the DRAM init source code, including DDR3 , > LPDDR3, > and LPDDR4(wip).

You are quite right about that, but I was thinking about the code to calculate DRAM timings (with link-training and such) which is often not available as free software, and I am not aware of Rockchip having released that code (but feel free to correct me if I'm wrong). > > > which would be the easiest and friendliest solution > > > towards the community here.

So I'm afraid I agree with Mark > at this time for the policy. Maybe we need to provide tools ot make that process easier for everyone if it is really that hard. I don't really see what is so special about DRAM timings that would imply that a regular developer doing a U-Boot bringup couldn't figure things out, aside from the ability to dump said timings. > If all the other SoC platforms can have the same rule for DRAM init driver > is a mandatory instead of option, eg. brcom, qcom, mtk, omap, tegra, stm, > imx, aml, and all others, then I would very happy to follow the rule. > Rockchip is open for open source the DRAM driver, you have to know this > is the decision by the vendor, but not any of developers. > On rockchip platform, developers no need to concern about the DRAM > driver(which is pretty hard for most developers) because rockchip > already contribute it. Rockchip is indeed in a better position than other vendors where DRAM init may not be available (or when it's impossible to run U-Boot right after the bootrom and do the DRAM init itself because of e.g. abusive signature verification or lack of documentation). Since there is good DRAM support for Rockchip in place, we have an opportunity to push developers to do the right thing and contribute full support for the board. To me it is simply a matter of acknowledging that bootloader support for a board without DRAM init is not useful bootloader support. Since we have the code in place to support that, we can take the extra step and require that each board contribution be useful in that aspect. > For the time now, I know there will be full DRAM driver for rockchip SoC, > so the SoC/board support could be step by step: > U-Boot proper -> U-Boot + SPL(no DRAM init) ->U-Boot + SPL + TPL. > > As you can see the rockchip LPDDR4 driver send by Jagan, has 99 patches > in V2, you can't use static register configuration to do this, and maybe you > can't have a workable version if rockchip don't release it, but I don't > think it's > correct to make all those boards with lpddr4 float outside the mainline > support > because many developers are using the boards, they can only use vendor > branch > if the board not support by mainline. If mainline U-Boot can't support basic bootloader features such as DRAM initialization for these boards, I don't see the point in accepting support for them. It would be like submitting support for a board in Linux with a new CPU that is not supported and asking to boot Linux via a non-free shim before Linux to put the CPU in a legacy state that Linux can support. This would definitely not be okay and I don't see why the same shouldn't apply to U-Boot. > So I think merge those patches already make board work on mainline U-Boot > is pretty important for open source community. I don't think the patches make the boards work on mainline U-Boot since building and installing the resulting U-Boot binaries will result in a non-functional boot chain and brick the device.

I thought that LPDDR4 works the same as other types of DRAM where we have a dtsi array with timings configuration. Of course, some more registers need to be set up, but we already have support for that or it's quite close (for LPDDR4). > > > which is present for a good number of rockchip > > > boards. > > No, there is no rockchip board only have static DRAM register > configuration values, that maybe happens in other vendor. I was implying that, as far as I know, it is the case for DRAM timings on Rockchip as well as most of the platforms that I know of. In the end, any code handling DRAM will end up writing timings to the controller's registers. If the DRAM is part of the PCB and doesn't change/move, then the timings don't change in particular. Is there something specific about Rockchip that makes it require different DRAM timings at each boot? > > > Of course, it would be best if Rockchip would consider releasing this > > > source code, > > Rockchip already release all the DRAM init source code, including DDR3 , > LPDDR3, > and LPDDR4(wip).

Rockchip is indeed in a better position than other vendors where DRAM init may not be available (or when it's impossible to run U-Boot right after the bootrom and do the DRAM init itself because of e.g. abusive signature verification or lack of documentation). Since there is good DRAM support for Rockchip in place, we have an opportunity to push developers to do the right thing and contribute full support for the board. To me it is simply a matter of acknowledging that bootloader support for a board without DRAM init is not useful bootloader support. Since we have the code in place to support that, we can take the extra step and require that each board contribution be useful in that aspect. > For the time now, I know there will be full DRAM driver for rockchip SoC, > so the SoC/board support could be step by step: > U-Boot proper -> U-Boot + SPL(no DRAM init) ->U-Boot + SPL + TPL. > > As you can see the rockchip LPDDR4 driver send by Jagan, has 99 patches > in V2, you can't use static register configuration to do this, and maybe you > can't have a workable version if rockchip don't release it, but I don't > think it's > correct to make all those boards with lpddr4 float outside the mainline > support > because many developers are using the boards, they can only use vendor > branch > if the board not support by mainline.

Linux build target is Image/zImage, if this Image not work with the board, eg. hang somewhere during boot, then we say the board support is broken and result in non-functional boot. And there always some kernel features depends on bootloader setting, including security setting, some clock init, some power supply and etc. > >> So I think merge those patches already make board work on mainline U-Boot >> is pretty important for open source community. > I don't think the patches make the boards work on mainline U-Boot since > building and installing the resulting U-Boot binaries will result in a > non-functional boot chain and brick the device.

If the standalone u-boot.bin or u-boot-spl.bin works good with a board and able to boot into next stage correctly, I don't think these patches can be consider as "non-functional boot chain and brick the device".

Linux build target is Image/zImage, if this Image not work with the board, eg. hang somewhere during boot, then we say the board support is broken and result in non-functional boot. And there always some kernel features depends on bootloader setting, including security setting, some clock init, some power supply and etc. > >> So I think merge those patches already make board work on mainline U-Boot >> is pretty important for open source community. > I don't think the patches make the boards work on mainline U-Boot since > building and installing the resulting U-Boot binaries will result in a > non-functional boot chain and brick the device.

If the standalone u-boot.bin or u-boot-spl.bin works good with a board and able to boot into next stage correctly, I don't think these patches can be consider as "non-functional boot chain and brick the device". And for example for armv8, U-Boot is always as part of the boot chain. Thanks, - Kever > > Cheers, > > Paul > >> Thanks, >> - Kever >>> Frankly, I don't think that would help.

Keeping allowing a step-by-step approach could be beneficial I think, in the kernel we also don't require full support for all peripherals on initial submission ;-) . And also for people starting out on a specific board having at least partial support is way easier than trying to figure out for example the vendor u-boot. Maybe we could give this some sort of time limitation like "binary ddr-init allowed till 2019-10-31" in Kconfig or somewhere to give people the chance to do things piece by piece but still force them to actually work on improving the situation. As driver-side changes will generally benefit more socs/boards potential removal after the time limit would only affect the board+dts itself. So somewhat similar to what the kernel does with "staging", if you keep working on improving it, it is allowed to stay. This could be also applied to already included boards, like "give it a working ddr-init till 2019-12-31 or it gets removed", similarly to how Tom handles devicemanager conversions currently > >> As you can see the rockchip LPDDR4 driver send by Jagan, has 99 patches > >> in V2, you can't use static register configuration to do this, and maybe you > >> can't have a workable version if rockchip don't release it, but I don't > >> think it's > >> correct to make all those boards with lpddr4 float outside the mainline > >> support > >> because many developers are using the boards, they can only use vendor > >> branch > >> if the board not support by mainline. > > If mainline U-Boot can't support basic bootloader features such as DRAM > > initialization for these boards, I don't see the point in accepting > > support for them. Hmm, actually I see ddr-init as one of the more difficult parts to achieve at least if you're not the soc-vendor, due to unavailable documentation or sources. > > It would be like submitting support for a board in Linux with a new CPU > > that is not supported and asking to boot Linux via a non-free shim > > before Linux to put the CPU in a legacy state that Linux can support. > > This would definitely not be okay and I don't see why the same > > shouldn't apply to U-Boot. A less drastic example would be, submitting a basic devicetree to the linux kernel without clocks and pinctrl and relying on the things the bootloader set up for things like uart.

Keeping allowing a step-by-step approach could be beneficial I think, in the kernel we also don't require full support for all peripherals on initial submission ;-) . And also for people starting out on a specific board having at least partial support is way easier than trying to figure out for example the vendor u-boot. Maybe we could give this some sort of time limitation like "binary ddr-init allowed till 2019-10-31" in Kconfig or somewhere to give people the chance to do things piece by piece but still force them to actually work on improving the situation. As driver-side changes will generally benefit more socs/boards potential removal after the time limit would only affect the board+dts itself. So somewhat similar to what the kernel does with "staging", if you keep working on improving it, it is allowed to stay. This could be also applied to already included boards, like "give it a working ddr-init till 2019-12-31 or it gets removed", similarly to how Tom handles devicemanager conversions currently > >> As you can see the rockchip LPDDR4 driver send by Jagan, has 99 patches > >> in V2, you can't use static register configuration to do this, and maybe you > >> can't have a workable version if rockchip don't release it, but I don't > >> think it's > >> correct to make all those boards with lpddr4 float outside the mainline > >> support > >> because many developers are using the boards, they can only use vendor > >> branch > >> if the board not support by mainline. > > If mainline U-Boot can't support basic bootloader features such as DRAM > > initialization for these boards, I don't see the point in accepting > > support for them. Hmm, actually I see ddr-init as one of the more difficult parts to achieve at least if you're not the soc-vendor, due to unavailable documentation or sources. > > It would be like submitting support for a board in Linux with a new CPU > > that is not supported and asking to boot Linux via a non-free shim > > before Linux to put the CPU in a legacy state that Linux can support. > > This would definitely not be okay and I don't see why the same > > shouldn't apply to U-Boot. A less drastic example would be, submitting a basic devicetree to the linux kernel without clocks and pinctrl and relying on the things the bootloader set up for things like uart.

To be fair, I'm not suggesting that either, I'm only concerned about DRAM init which I wouldn't put under "any feature/controller" but one of the basic things that are required to make bootloader support useful. > And also for people starting out on a specific board having at least partial > support is way easier than trying to figure out for example the vendor > u-boot. Fair enough, but it can also bring some confusion if support is not clearly identified as being partial. Hence my point about inadvertently bricking devices if U-Boot alone is sufficient to boot on some rk3399 devices but if it's not on some other ones. > Maybe we could give this some sort of time limitation like > "binary ddr-init allowed till 2019-10-31" in Kconfig or somewhere > to give people the chance to do things piece by piece but still force them > to actually work on improving the situation.

That is true, but I don't see this as a good reason to lower our standards. Instead, I believe we should push for vendors to release said source code and documentation, or for the community to reverse- engineer DDR init. Again, this is a less pragmatic approach but a more strategic and political one. To me it's all about whether U-Boot as a project wants to focus on technical aspects only and follow along on the political side (which is not to say that it is politically neutral, the status quo is very much a political stance) or if U-Boot wants to take a stand here and use the power it has accumulated over the years to do things right and push in the right direction. > > > It would be like submitting support for a board in Linux with a new CPU > > > that is not supported and asking to boot Linux via a non-free shim > > > before Linux to put the CPU in a legacy state that Linux can support. > > > This would definitely not be okay and I don't see why the same > > > shouldn't apply to U-Boot. > > A less drastic example would be, submitting a basic devicetree to the > linux kernel without clocks and pinctrl and relying on the things the > bootloader set up for things like uart.

To be fair, I'm not suggesting that either, I'm only concerned about DRAM init which I wouldn't put under "any feature/controller" but one of the basic things that are required to make bootloader support useful. > And also for people starting out on a specific board having at least partial > support is way easier than trying to figure out for example the vendor > u-boot. Fair enough, but it can also bring some confusion if support is not clearly identified as being partial. Hence my point about inadvertently bricking devices if U-Boot alone is sufficient to boot on some rk3399 devices but if it's not on some other ones. > Maybe we could give this some sort of time limitation like > "binary ddr-init allowed till 2019-10-31" in Kconfig or somewhere > to give people the chance to do things piece by piece but still force them > to actually work on improving the situation.

That is true, but I don't see this as a good reason to lower our standards. Instead, I believe we should push for vendors to release said source code and documentation, or for the community to reverse- engineer DDR init. Again, this is a less pragmatic approach but a more strategic and political one. To me it's all about whether U-Boot as a project wants to focus on technical aspects only and follow along on the political side (which is not to say that it is politically neutral, the status quo is very much a political stance) or if U-Boot wants to take a stand here and use the power it has accumulated over the years to do things right and push in the right direction. > > > It would be like submitting support for a board in Linux with a new CPU > > > that is not supported and asking to boot Linux via a non-free shim > > > before Linux to put the CPU in a legacy state that Linux can support. > > > This would definitely not be okay and I don't see why the same > > > shouldn't apply to U-Boot. > > A less drastic example would be, submitting a basic devicetree to the > linux kernel without clocks and pinctrl and relying on the things the > bootloader set up for things like uart.

Otherwise you're just punishing Rockchip for having a partial DRAM initialization code and are potentially sending the message that it's better not to attempt create open source DRAM drivers. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot ^ permalink raw reply [flat|nested] 43+ messages in thread

I'm not following this at all. Rockchip has a particular situation where almost all the boards have free DRAM init, which is not the case on every platform. I don't see why this decision has to be harmonized on the whole project since I believe it only makes sense for the specific case of Rockchip. Seeing this as some sort of punishment feels like a gross misinterpretation of our intent. If we are clear and communicate about the motivations why we think this is important and why this rule is applied, then there is nothing we can do about mis-judgments. I don't think it's fair or rational to not take action because of that. Whatever we do, there is always a chance that people will mis-interpret things and throw shit at us for taking political decisions. That's too bad, but there is only so much we can do about that. And rest asured that people (including myself) can also throw shit at the project for maintaining a weak status-quo and not contribute to moving things forward on political aspects when it is in a power position to do so.

I was talking about time-limiting the use of the _binary_ loader (as TPL or whatever) from Rockchip's rkbin repo [0]. Which would mean no sourceful ddr-driver at all. That case (using the binary) is a nice stepping stone to iterative development, as you can concentrate on other parts of the boot process, but when it overstays its welcome things begin to rot. An example could be the rk3128 included in u-boot, no ddr-init at all (requiring the binary ddr-init) and also no plans at all to create u-boot- based ddr-init in the future. And the soc is so niche, that it sees no real development. In turn I would welcome any approach for a sourceful ddr-init as valid. Because once you have something that at least works, you can iterate on improving it.
