SH get devicetree support. But it not working on existing H/W.
IO-DATA HDL-U (aka landisk) currentry supported.
This H/W like SH7751 evalution board. It's a best to use this as a
change base H/W.
RTS7751R2Dplus is QEMU-SH4 target. So easy trying.
Changes V5
- added "#address-cells" before interrupt-map
- remove interrupt-controller of landisk.dts and r2dplus.dts
- Add ".suppress_bind_attrs" to pci driver.
- some cleanup.
Changes V4
- split board depend patch.
- dts cleanup.
Changes V3
- PCI driver update for v4.7.
- New Clock driver. Unified PLL/Divider.
- R2Dplus support.
- Split DTS.
- Some cleanup.
Changes V2
- split DeviceTree suppoty update.
- PCI driver update.
- Some cleanup.

sh used P1 address space in early device tree.
So need convert P1 to physical address before reserve memory.

SH3/4 have register bank of R0-R7.
Preset FDT address assigned bank depend on boot loader.
Before setting a bank because we don't depend on a boot loader, it's evacuated.

Cc: Yoshinori Sato
This is an alternative SH7751 PCI driver.
Existing driver (arch/sh/drivers/pci/pci-sh7751) uses SH specific interface.
But this driver uses common PCI interface. It is more modern and generic.

+Required properties:
+ - compatible: "renesas,sh7751-pci" is required.
+ And board specific compatible if fixup required.
+ - reg: contain two entries.
+ first entry: PCI controller register base address and length.
+ second entry: BUS controller register base address and length.
+ - #address-cells: set to <2>
+ - #size-cells: set to <1>
+ - bus-range: PCI bus numbers covered
+ - device_type: set to "pci"
+ - ranges: ranges for the PCI memory and I/O regions.
+ - interrupt-map-mask and interrupt-map: standard PCI properties
+ to define the mapping of the PCI interface to interrupt
+ numbers.

* [PATCH v6 12/22] sh: Add PCI host bridge driver for SH7751
@ 2016-07-03 16:46 ` Yoshinori Sato
0 siblings, 0 replies; 138+ messages in thread
From: Yoshinori Sato @ 2016-07-03 16:46 UTC (permalink / raw)
To: devicetree, linux-pci, linux-sh, linux-kernel; +Cc: Yoshinori Sato
This is an alternative SH7751 PCI driver.
Existing driver (arch/sh/drivers/pci/pci-sh7751) uses SH specific interface.
But this driver uses common PCI interface. It is more modern and generic.

+* Renesas SH7751 PCI host interfaces

+Required properties:
+ - compatible: "renesas,sh7751-pci" is required.
+ And board specific compatible if fixup required.
+ - reg: contain two entries.
+ first entry: PCI controller register base address and length.
+ second entry: BUS controller register base address and length.
+ - #address-cells: set to <2>
+ - #size-cells: set to <1>
+ - bus-range: PCI bus numbers covered
+ - device_type: set to "pci"
+ - ranges: ranges for the PCI memory and I/O regions.
+ - interrupt-map-mask and interrupt-map: standard PCI properties
+ to define the mapping of the PCI interface to interrupt
+ numbers.
+

This is an alternative SH7751 PCI driver.
Existing driver (arch/sh/drivers/pci/pci-sh7751) uses SH specific interface.
But this driver uses common PCI interface. It is more modern and generic.

+* Renesas SH7751 PCI host interfaces
+
+Required properties:
+ - compatible: "renesas,sh7751-pci" is required.
+ And board specific compatible if fixup required.
+ - reg: contain two entries.
+ first entry: PCI controller register base address and length.
+ second entry: BUS controller register base address and length.
+ - #address-cells: set to <2>
+ - #size-cells: set to <1>
+ - bus-range: PCI bus numbers covered
+ - device_type: set to "pci"
+ - ranges: ranges for the PCI memory and I/O regions.
+ - interrupt-map-mask and interrupt-map: standard PCI properties
+ to define the mapping of the PCI interface to interrupt
+ numbers.
+
+Example:
+ pci: pci-controller@fe200000 {
+ compatible = "renesas,sh7751-pci", "iodata,landisk";
+ device_type = "pci";
+ bus-range = <0 0>;

+DT bindings for the Renesas R0P751RLC0011RL (R2Dplus) interrupt controller
+
+Required properties:
+
+ - compatible: has to be "renesas,r2dplus-intc".
+
+ - reg: Base address and length of interrupt controller register.
+
+ - #interrupt-cells: has to be <1>: an interrupt index.
+
+ - #address-cells: has to be <0>
+
+ - interrupt-map: Interrupt mapping on parent controller.
+
+Example
+-------
+
+ fpgaintc: fpga@a4000000 {
+ compatible = "renesas,r2dplus-intc";
+ #interrupt-cells = <1>;
+ #address-cells = <0>;

I think all of this code should be in appropriate driver files, not
of-generic.c. Much of it looks like it should be pm (power management)
drivers for which I'd assume there's an existing framework. I'm not
sure about the DRAM control. For the LED I think there's an LED GPIO
framework already too that would be appropriate and that probably
only needs appropriate nodes in the DT, not even any code.

I don't think this change is correct, and I'm not sure what the
motivation is. It certainly can't work with !CONFIG_29BIT, and likely
can't work on nommu either (it won't work on J2). Maybe we have
different ideas about the sort of physical address the boot loader is
expected to pass; I would expect it to be something that, when passed
to phys_to_virt, yields an address the kernel can use to access the
memory. This does not necessarily mean it's MMU-mapped memory; it
could be (and in practice will be, I think) an address in the P1
segment obtained by adding PAGE_OFFSET (see asm/page.h).

Is this code specific to particular PCI bus hardware on Renesas SH
systems? If so it probably should be kept as a driver file rather than
in arch/sh/kernel core, but I don't actually see a lot of code that
looks hardware-specific. If there's not actually much or anything
hardware-specific about it, could we perhaps unify it with other PCI
bus support code outside or arch/sh?

Is this code specific to particular PCI bus hardware on Renesas SH
systems? If so it probably should be kept as a driver file rather than
in arch/sh/kernel core, but I don't actually see a lot of code that
looks hardware-specific. If there's not actually much or anything
hardware-specific about it, could we perhaps unify it with other PCI
bus support code outside or arch/sh?

I think we need a consistent form of physical memory addressing in the
DT that doesn't require this. Hard-coding details of the segmented
memory model all over the place does not look like a good idea; it's
going to badly break anything with full 32-bit which I believe some
SH-4 models had (those with PMB?) and which J3/J4 will almost
certainly have.

Even 32 bits mode are assigned to the same area now.
But lookup PMB more better.
It add "#ifdef CONFIG_29BIT".

I still don't think there should be any sh-specific code here. Can you
explain why you think it's needed with an example including real
addresses and how they'd get mapped incorrectly without this patch?

I think we're just having a miscommunication on what "physical
address" vs "virtual address" means. I wouldn't call logical addresses
in the P1 segment "virtual" because they're not remapped by the MMU.
Could you provide an example showing the type of address your
bootloader is currently passing to the kernel and why it needs to be
mapped by P1SEGADDR rather than phys_to_virt?

What is evt2irq? We only allow simple defines for DT files, not complex
macros.
Spaces around the '=' also needed.

I'd like some details here about why we want this new driver. Will
the old one be removed? How should a user choose which one to use?

How do you plan to merge this? It looks like part of a large series,
and I've only seen a few pieces of it. The ones you've posted to
linux-pci seem mostly OK. I have a few minor comments below, but
after you fix those and write some text for the changelogs, I can ack
them and you can merge them along with the rest of the series.

Field names are unused. You do write 0xc3ff to SH4_PCIINTM, but it's
a pain to match that up with these definitions. Either write out the
masks here, e.g., "#define SH4_PCIINTM_MRDPEIM 0x00000001", or build
up the SH4_PCIINTM from these definitions, or both.

I'd like some details here about why we want this new driver. Will
the old one be removed? How should a user choose which one to use?

How do you plan to merge this? It looks like part of a large series,
and I've only seen a few pieces of it. The ones you've posted to
linux-pci seem mostly OK. I have a few minor comments below, but
after you fix those and write some text for the changelogs, I can ack
them and you can merge them along with the rest of the series.

Field names are unused. You do write 0xc3ff to SH4_PCIINTM, but it's
a pain to match that up with these definitions. Either write out the
masks here, e.g., "#define SH4_PCIINTM_MRDPEIM 0x00000001", or build
up the SH4_PCIINTM from these definitions, or both.

I'd like some details here about why we want this new driver. Will
the old one be removed? How should a user choose which one to use?

How do you plan to merge this? It looks like part of a large series,
and I've only seen a few pieces of it. The ones you've posted to
linux-pci seem mostly OK. I have a few minor comments below, but
after you fix those and write some text for the changelogs, I can ack
them and you can merge them along with the rest of the series.

Field names are unused. You do write 0xc3ff to SH4_PCIINTM, but it's
a pain to match that up with these definitions. Either write out the
masks here, e.g., "#define SH4_PCIINTM_MRDPEIM 0x00000001", or build
up the SH4_PCIINTM from these definitions, or both.

This patch series - which would make a huge improvement - is still not
applied. It would be very useful to be able to test the device tree
implementation with QEMU.
Any of the SH maintainers can apply this?

It's Rich's call, but given that it's _from_ one of the sh maintainers,
sounds to me like it can just go in if it still applies? (If there's
bugfixes needed they can go in -rc2 or so, after this merge window.)
Given that qemu serial's been broken for 9 months now, I doubt this
would make anything worse. (I should really check Cedric's qemu fork to
see if he fixed that...)

There were significant problems that I don't think were ever
addressed, including incompatible changes in how boot command line was
handled and possibly ambiguity about what a physical address means
(zero based vs based in the zone SH3/4 excludes from MMU mapping) in
the contract for how the bootloader passes a DTB pointer in to the
kernel, or something similar.
This is a large part of why I want to get to the point where I can
build and boot a kernel on the LANDISK -- not being able to test any
of this is a blocker for moving everything to device tree.

I see, thanks for the heads-up.

I can actually help you with that. I know what to do to get the kernel
to boot on the LANDISK device. I've got everything working except
being unable to detect the IDE controller. The attached config builds
a kernel which boots with the attached output.
Furthermore, in order to install the kernel, you need to use the
cross-LILO version from [1] which allows to install the bootloader
on an x86 machine into the SuperH LANDISK image.
Instructions can be found in [2]. A base filesystem can be found in [3].
And I could also send you an USL-5P which is also a LANDISK device,
just in a different form-factor.

I'm trying to reproduce this but can't find any documentation for
cross-LILO in [2], much less any code except possibly the binary
"lilo.x86" in [1]. Googling cross-lilo isn't finding anything
meaningful except this thread. Is there anywhere to find source and
information on what it's doing, or is this going to be something I
have to reverse-engineer?

It's just LILO for x86, nothing fancy. You could as well just download
LILO, build it for x86 and then use it to install the bootloader onto
the harddisk/CF medium you are using on the LANDISK.
Source code for LILO can be found here: https://lilo.alioth.debian.org/
It's a simple bootloader which works with blocklists.

OK, it's good to know that the lilo program is just stock lilo. So
is the provided boot.b-selk file (and an appropriate lilo.conf) all
you need to get it installed on a disk?

If I remember correctly, yes. What you need should be obvious from
the supplied lilo.conf. In order to get LILO to install from my normal
x86 machine, I just bind-mounted the /boot folder of the target hard
disk (CF medium in the case of the USL-5P) and ran the lilo command
with the block device of the target hard disk as a parameter.
It's a bit hacky and it took me some trial and error to get it working,
but I was eventually able to boot a self-compiled kernel on one of
my USL-5Ps. Only issue I initially had was that the bus clock(?) was
set to an incorrect value in the kernel config. With the bus clock
set incorrectly, the kernel would just freeze up.
Oh, and I never managed to get the kernel detect the pseudo-IDE
controller of my USL-5P device. It might work better with your
HDL-160U.

Progress on all this! I've got my LANDISK working again, but with the
disk image Sato-san provided me, which is using (a patched?) U-Boot
and a kernel based on this patch series. I don't know how to recreate
the U-Boot setup from scratch, but I might be able to figure out how
to replace the kernel image it's using. It's possible I may be able to
get lilo working too -- I tried building it but I'm still not sure how
to use it, and in any case I need to image the existing system before
I clobber it since I'm not sure I have the original image.
On a better note, I've reviewed this patch series in more depth and
understand it pretty well now, and have classified the patches as
follows:
01-04 -- about P1 vs absolute interpretation of "physical addresses",
and can be completely dropped if we just use the latter. The former
does not work with full-32-bit address space.
05 -- change in command line interpretation. Something like this might
be desired at some point, if we make it non-conflicting with current
use, but it's independent and not needed.
06-09 -- extending arch/sh device tree support with functionality
needed to get traditional sh systems using it. These look roughly ok,
but might need minor cleanup. Just applying these and linking in a
minimal DTB, I should be able to get a non-board-specific kernel that
boots and shows console messages until it gets stuck with no interrupt
controller or devices. This is the milestone I'm looking to get to
first.
10 -- LANDISK board-specific init stuff, moved into of-generic.c. This
is not where it belongs, but I don't know where it should be, or if we
can get it to book without this. If not, it can be applied as a hack
for testing.
11-13,19 -- new style device tree drivers for clock, pci bus, and irq
controller. They'll have to go through subsystem maintainers unless we
want to move them into arch/sh/drivers. Without these the system is
not going to be usable to the point of reaching userspace.
14,20 -- device trees. The evt2irq/irq2evt macros probably don't make
sense and should be either irqdomain mappings or just removed. But
these can be used out-of-tree anyway to make a DTB while testing.
15-17 -- might also be needed for PCI to work. Not sure about them.

I found the U-Boot stuff here:

but I'm not sure how to install it yet. Will try to figure it out.

Interesting. It seems the HDL-160U uses u-boot instead of lilo which
is used on my USL-5P. Both are based on the LANDISK platform though.
I wonder whether it is possible to convert the USL-5P to use u-boot
instead of the very limited lilo.
As for the kernel configuration, for USL-5P, I had to use the kernel
configuration attached to this mail. One important configuration setting
is CONFIG_SH_PCLK_FREQ which has to be set to "33250000" otherwise
the kernel won't boot properly.
I still have my USL-5P ready to be set up for testing a new kernel
image with the device tree patches merged. Although I still don't
know how to enable the internal (pseudo) IDE controller.
@Yoshinori:
Did the HDL-160U LANDISK device you have use u-boot by default or
did you convert it from lilo?

Interesting. It seems the HDL-160U uses u-boot instead of lilo which
is used on my USL-5P. Both are based on the LANDISK platform though.
I wonder whether it is possible to convert the USL-5P to use u-boot
instead of the very limited lilo.
As for the kernel configuration, for USL-5P, I had to use the kernel
configuration attached to this mail. One important configuration setting
is CONFIG_SH_PCLK_FREQ which has to be set to "33250000" otherwise
the kernel won't boot properly.
I still have my USL-5P ready to be set up for testing a new kernel
image with the device tree patches merged. Although I still don't
know how to enable the internal (pseudo) IDE controller.
@Yoshinori:
Did the HDL-160U LANDISK device you have use u-boot by default or
did you convert it from lilo?

The above U-Boot seems to be a version that's installed in the MBR and
then loads a second-stage program (from where, though?). It's not a
flash rom replacement as far as I can tell -- at least I never did
anything with the flash, and I think before I loaded this disk image,
it was using lilo. I probably still have the original drive that was
in it, with whatever that was booting from.

Yes.
Replace sh-lilo's second stage with u-boot.
With this method it is unnecessary to rewrite Flash for boot.

Great, thank you. I will give it a try on my USL-5P and write down
the individual steps once I have figured it out.
As for the IDE controller: Can you tell me whether there are any
particular patches necessary to get the kernel detect the IDE
controller of the LANDISK devices?
I have been able to boot my own kernel on my USL-5P device, but
I could never get it to detect the IDE controller. Do I need
an additional patch for that?

On a related note, is there a list of boards anywhere? I'm working on a 7760
system at $DAYJOB, Rich has a landisk which according to
https://www.openbsd.org/landisk.html is an SH7751R, and Sato-san says that
QEMU's -r2d emulates that too? ("RTS7751R2Dplus is QEMU-SH4 target. So easy
trying.")
What other boards do we need to covert to device tree? arch/sh/boards has 15 C
files and 19 subdirectories, but I dunno the status of any of them...

I have lots of Dreamcasts (SH7091), one SH7785LCR evaulation board and one
SH7724 Evovec board. I also own one KMC KZ-SH3-03 (SH7708, SH-3) board and
several small SH-2 and SH-2A boards (from a Japanese electronics magazine).
I think Geert Uytterhoven has also one SH-4 board (if I remember correctly)
and one of the gcc upstream maintainers has an AP-SH4AD-0A board from Alpha
Project.

Hard to say. At least the ones above plus the ST-40 boards should be included.
I would leave the rest in for the time being unless they become a burden
in any way.
First we should get Sato-san's LANDISK device tree conversion merged though
and maybe we can use this one as a template to convert the rest. I would
be happy to help.

Sorry to disappoint you, but my SH-4A CPU cores are buried in Renesas ARM SoCs.
Using those means resurrecting "SH Core Linux" and forward-porting it to
still-supported SoCs first.

I also have access to a remote Migo-R (SH7722).

I think asking "what we need to convert" is at least slightly
mis-framed. Once the basics for device tree support are in place
(basically patches 06-09), which boards are supported by device tree
is mostly a matter of (1) whether the hardware drivers you want to use
have bindings and use modern kernel interfaces, and (2) someone
writing the dts files.
Unless there's strong objection, I'd be happy with just doing a survey
of device drivers used on currently supported boards, making sure they
all nominally support device tree, then removing the old board file
framework and waiting to see user response. If we take this path it
should likely happen in a release not planned for LTS so there's time
to add appropriate driver fixes and dts files before the next LTS
release.
I don't mind holding off a little bit on removal of the legacy board
file support if it's hard to get enough hardware working right away
with device tree, but I do want to move towards getting rid of it as
soon as we can, since it's a large volume of code cutting into my
ability to have a good maintainer-level understanding of the arch/sh
tree and has a lot of crufty, unmaintained parallel infrastructure
duplicating stuff that can be done in cleaner and more modern ways
(see the threads on early platform device stuff, rtc drivers, etc.).

Please let me know once you figure it out. I haven't made much
progress yet and it would be really helpful to have some simple
directions/outline of what to do, especially one that's not in terms
of black box tools ("run this command") but how it all works (where
the different bootloader components live when installed -- MBRs?
partition boot records? files in a filesystem (who interprets it?)?
etc.)

We can _add_ device tree support without that, but can we remove the old board
files without it?

The process may include a deprecation of hardware nobody has anymore, with call
for testers, for a year or so before deleting stuff. (And then the old stuff's
in git if somebody finds a board and wants to fish it out.)
Also, I'd really like QEMU support to act as a first class board. At least 256
megs of ram (so you can do native compiles on it), serial support that works
(enabling the FIFO broke it because they don't implement the '15 bits of silence
triggers a flush timer' part, so data gets stranded in the buffer until enough
comes in to fill it the rest of the way which is a pain to type at when it's a
serial console), multiple hard drives, and so on.
I'd be fine with virtio but there's no virtio devices on that target I've
noticed yet, although maybe I just haven't figured out how to enable it...

U-boot 101. The workflow you want is usually:
1) get u-boot to load and run on the board, with serial console and a basic
knowledge of where the DRAM is. (This often involves fighting with dram refresh
init, often by convincing u-boot NOT to do it because your stage 1 bootloader
already did, which involves a rolled up newspaper and a lot of swearing because
it ASSUMES. Oh it assumes. Or sometimes there's an sram->dram relocation which
means somewhere, there's a magic linker script you will learn to hate. Well,
Rich might be comfortable with that area, I still stub my toes there a lot.)
2) Getting u-boot reading/writing a flash area it can store its environment
variables in, so they can persist. (It's a driver.)
3) get u-boot talking to the network card, with either dhcp or static IP.
(Another driver, and some magic environment variables the driver consumes.)
4) tftp fetch an ELF kernel (or uimage if you must) into DRAM starting at a
known address. (This is a u-boot command line command. You'll need a tftp server
set up on another machine for it to fetch from.)
5) tftp fetch any other data (initrd.cpio.gz, board.dtb). (Same command,
different parameters.)
6) boot the kernel with all that gorp (a big long command line command) which
will need a kernel command line (generally stored in another persistent
environjment variable).
7) make a "go" script that does all that in one commend. There's a command to
run an environment variable's contents as a set of semicolon-separated command

U-boot 101. The workflow you want is usually:
1) get u-boot to load and run on the board, with serial console and a basic
knowledge of where the DRAM is. (This often involves fighting with dram refresh
init, often by convincing u-boot NOT to do it because your stage 1 bootloader
already did, which involves a rolled up newspaper and a lot of swearing because
it ASSUMES. Oh it assumes. Or sometimes there's an sram->dram relocation which
means somewhere, there's a magic linker script you will learn to hate. Well,
Rich might be comfortable with that area, I still stub my toes there a lot.)
2) Getting u-boot reading/writing a flash area it can store its environment
variables in, so they can persist. (It's a driver.)
3) get u-boot talking to the network card, with either dhcp or static IP.
(Another driver, and some magic environment variables the driver consumes.)
4) tftp fetch an ELF kernel (or uimage if you must) into DRAM starting at a
known address. (This is a u-boot command line command. You'll need a tftp server
set up on another machine for it to fetch from.)
5) tftp fetch any other data (initrd.cpio.gz, board.dtb). (Same command,
different parameters.)
6) boot the kernel with all that gorp (a big long command line command) which
will need a kernel command line (generally stored in another persistent
environjment variable).
7) make a "go" script that does all that in one commend. There's a command to
run an environment variable's contents as a set of semicolon-separated command
line commands (that's how u-boot implements scripts), and there's a magic
environment variable whose contents get run on startup (bootup? startup? I
forget, it's in the source and docs and a buncha examples out there). It's
cleaner to have the magic one do "run $othervar" rather than putting a lot of
plumbing in the magic one. And you will totally want a "wait 3 seconds for a key

As far as what Linus told me when I joined as maintainer, we can
remove whatever we like. But I don't want to be user-hostile.
OTOH I don't think there are SH users keeping up with bleeding-edge
kernels, and I don't think distros (Debian?) are shipping kernels
anyway since the kernel is currently highly board-specific. So the
only users who would be affected by removal are ones building their
own latest kernels, and it seems plausible they'd be happy with doing
a little testing to provide feedback to get things working with DT if
they don't work out of the box.

Unfortunately the r2d has some hardware mapped just above 64M
physical, so it's not easy to extend its memory size. I think device
tree will solve this by letting us pass multiple physical ranges that
can be used as ram, which I don't know how to do with the old
kconfig-based memory base/size.
Of course there's no limit (except the usual 2G one) on virtual
memory, so another solution is just adding large swap. I think with a
virtio block device it would be fast.

Let's look at how the kernel detects the buffer capability. It might
be a one-line fix on the qemu side, telling it to claim to emulate an
older model, and it's probably easy to add a kernel cmdline option to
work around it too.

I'm running qemu-sh4-system with -M r2d and virtio 9p & network,
rootfs on 9p. If you want to try reproducing my setup I can run
through my .config and command line options with you and see if we can
get something in suitable form for writeup.

This sounds like a pain, but none of it seems relevant to the setup
we're using. This U-Boot variant does not install on flash or use
flash; it runs from disk in place of LILO or another MBR-based
bootloader. I'm just trying to understand where/how the binary blobs
are installed on the disk so I can reproduce that when making new disk
images with my kernel and filesystem.

That's the full dance for getting it installed on a board it's not already
running on. Usually somebody else sets it up and you inherit one with a "tftp
download" script and another "boot from persistent storage" script and you
mostly just the command line to swap the autoboot variable to point to the right
one of the two.

The point of the tftp boot is quick reboot cycles during development, not having
to install the kernel you're booting on target each time. But as long as you're
not replacing u-boot and have a u-boot console you can fall back on an alternate
kernel from disk. (It's not really designed to give you a menu though, it gives
you a command line. You can have the kernel name to load in its own variable and
"set kernelname 'walrus.img'; run hdboot" though.)

That's the full dance for getting it installed on a board it's not already
running on. Usually somebody else sets it up and you inherit one with a "tftp
download" script and another "boot from persistent storage" script and you
mostly just the command line to swap the autoboot variable to point to the right
one of the two.

The point of the tftp boot is quick reboot cycles during development, not having
to install the kernel you're booting on target each time. But as long as you're
not replacing u-boot and have a u-boot console you can fall back on an alternate
kernel from disk. (It's not really designed to give you a menu though, it gives
you a command line. You can have the kernel name to load in its own variable and
"set kernelname 'walrus.img'; run hdboot" though.)
There are probably more elegant ways to use this tool. I learned how to hammer
it in and get the lid off, and went on to other things...

I have not changed it in particular.
It works with AEC-62XX.

Can you give me a brief explanation of how to reproduce the bootloader
installation? For now I'm just using the existing MBR/partitioning you
sent me, and replacing zImage.itb in /boot makes it attempt to load a
new kernel, but I haven't gotten any output yet to know if it's
working.
Probably the most important thing I'm missing right now is what the
its file for generating the zImage.itb should look like. I tried
making one myself but it may be wrong. I'm also unsure whether I
should use a zImage or vmlinux file as input, and if using a zImage
file, what load address I should choose.
For now I'm using the upstream landisk board support (maybe not
working, we'll see). Once I can confirm I'm getting some output and
the kernel seems minimally functional, I'm going to switch to DT, but
integrating the DT stuff with u-boot isn't important right away since
I can start with a linked-in DT.
At some point I'd also like to know how to reinstall u-boot on the MBR
or whatever.

landisk's u-boot using spl.
You should be able to update it by the following procedure.
1. Rebuild u-boot.
2. Format ext4 for HDD first partition.
3. put u-boot.img to HDD first partition.
4. put spl/u-boot-spl.bin to HDD MBR and subsequent region.

I will try to set up uboot this way on my USL-5P over the weekend.
