[U-Boot] [PATCH 00/31] ARM: k2g: Add support for new K2G ICE EVM.

[U-Boot] [PATCH 00/31] ARM: k2g: Add support for new K2G ICE EVM.

[Franklin S Cooper Jr]

This patchset adds support for the new Keystone 2 Industrial Communication
Engine board.

This patchset includes the introduction of embedded FIT images in U-boot.
This creates a FIT image of dtb files that enables board specific code to
select which DTB to use at runtime. Initially during boot a generic DTB is
required that enables board detection to occur and once it has can later be
swapped out for the correct dtb.

    of FIT

[U-Boot] [PATCH 01/31] ti: common: board_detect: Allow settings board detection variables manually

[Franklin S Cooper Jr]

From: Nishanth Menon <nm@ti.com>

In some situations the EEPROM used for board detection may not be
programmed or simply programmed incorrectly. Therefore, it may be
necessary to "simulate" reading the contents of the EEPROM to set
appropriate variables used in the board detection code.

This may also be helpful in certain boot modes where doing i2c reads
may be costly and the config supports running only a specific board.

[U-Boot] [PATCH 02/31] spl: fit: Break out some functions into a common file

[Franklin S Cooper Jr]

Some of the functions within spl_fit will be used for non spl purposes.
Instead of duplicating functions simply break the functions to be reused
into its own file.

[U-Boot] [PATCH 03/31] boot_fit: Create helper functions that can be used to select DTB out of FIT

[Franklin S Cooper Jr]

Some platforms may append a FIT image to the U-boot image. This function
aids in parsing the FIT image and selecting the correct DTB at runtime.

[U-Boot] [PATCH 04/31] fdt: Enable selecting correct DTB from append FIT Image

[Franklin S Cooper Jr]

This patch gives U-boot the runtime support to have the board specific
code decide which FDT to use. This is especially useful for devices
that need this type of runtime determination and also doesn't use SPL.

[U-Boot] [PATCH 05/31] ti: common: board_detect: Add function to determine if EEPROM was read

[Franklin S Cooper Jr]

When the EEPROM is first read its contents are stored in memory as a
cache to avoid further I2C operations. To determine if the EEPROM was
previously read the easiest way is to check the memory to see if the
EEPROM's magic header value is set. Create a new function that can
determine if the EEPROM was previously read or not without having to
perform a I2C transaction.

[U-Boot] [PATCH 12/31] board_f: Add new function to allow runtime DTB selection

[Franklin S Cooper Jr]

Runtime U-boot dtb selection is generally a two step process. First step
is to simply use an initial generic dtb. The second step is to select
the dtb and perhaps execute additional code ones U-boot knows what board
it is running on. Embedded_dtb_select handles the second step by allowing
board specific code to run and perform what ever necessary configuration
that is needed.

[U-Boot] [PATCH 15/31] ARM: k2g: Define embedded_dtb_select for runtime DTB selection in U-boot

[Franklin S Cooper Jr]

For K2G, runtime DTB selection utilitizes the embedded_dtb_select function.
Therefore, define the function which will perform a EEPROM read and then
retries selecting the correct dtb now that it can detect which board its
on. For other Keystone devices use an empty function since they will still
use the embedded FIT functionality but their FIT will only contain a single
dtb.

Most production K2G boards do not have their EEPROM programmed. Therefore,
perform a test to verify a K2G GP is currently being used and if it is then
set the values normally set by a EEPROM read.

[U-Boot] [PATCH 17/31] ks2_evm: Add EEPROM based board detection

[Franklin S Cooper Jr]

Some K2G evms have their EEPROM programming while most do not. Therefore,
add EEPROM board detection to be used as the default method and fall back
to the alternative board detection when needed.

Also reorder board configuration. Perform bare minimal configuration
initially since board detection hasn't ran. Finish board configuration
once the board has been identified.

[U-Boot] [PATCH 20/31] ARM: k2g: Program DDR PHY MR2 register with the default value

[Franklin S Cooper Jr]

K2G GP doesn't require the MR2 register to be programed since the
default is good enough. However, newer K2G boards do need to change
this register value. Therefore, instead of not writing this register if
ran on a K2G board just program the value to be written to match the
default/reset value.

[U-Boot] [PATCH 22/31] ks2_evm: Add EEPROM based board detection helper functions

[Franklin S Cooper Jr]

Add a function that can be used to determine if the board being ran on is
a K2G Industrial Communication Engine EVM or K2G General Purpose EVM based
on values programmed on the EEPROM.

[U-Boot] [PATCH 23/31] ARM: k2g: Add pinmux support for K2G ICE evm

[Franklin S Cooper Jr]

Add basic pinmux data for new K2G ICE evm. Also add pinmuxing for a
generic K2G evm which includes I2C 0 and 1 used for board detection
purposes.

Since multiple K2G boards are supported that means initially generic
pinmuxing should be used when board detection hasn't ran. Once board
detection runs the proper pinmuxing can be reran to match the board
being ran on.

[U-Boot] [PATCH 30/31] ARM: k2g: Add K2G ICE DTB to the list of possible DTBs

[Franklin S Cooper Jr]

K2G ICE evm will have its own dtb. Therefore, add it to the list of dtbs
located in the appended U-boot dtb FIT image. Therefore, when swapping out
dtbs K2G ICE boards can grab the correct one.

there's a micro-optimization for some cases here. You can try to read
i2c only on first time and save the result to environment. Something
like:

if (!getenv("serial#")) {
	read_serial_from_eeprom(&serial);
        setenv("serial#", serial);
        saveenv();
}

Of course, this assumes i2c is available and eeprom is properly
programmed. For bogus eeprom data, well, can't do much.

Atleast for the purposes I'm using it for I have to deal with non
programmed eeprom. The other usecase I've seen was wanting to avoid
touching the EEPROM at all.

I'll have to look at it closely again but from what I remember Andre's
series was adding additional functionality to functions within spl_fit
while I only care about making those same functions accessible beyond
SPL. So it depends on whose code is merged first but I don't think it is
a big problem to manage.

Lets start figuring out a better place for this information that's not
in include/configs/ so that when these files go away there'll be one
less thing to worry about.  There must be some reasonable
<asm/arch/xxxx> file that's common to all of the various platforms
already to place this in.  Thanks!

So I'm not 100% sure on how to proceed here exactly.  We have a few
things to consider.  First, I bet the generic dtb is good enough for
loading up and booting to Linux (and loading/passing a different,
complete and board specific DTB).  Second, we have the (reasonable)
set of patches and discussion to make the DTB that we use available
easily so that it could be passed on to Linux (or EFI apps or whatever).
So, this is probably the right thing to do in the long run, but is also
another data point in the "but we need to think and talk about if some
platforms really shouldn't be shipping their full FT on the HW
somewhere".

It might also happen that somebody would like to have one "blessed"
u-boot binary stored in one place and then only change u-boot DTB stored
on another memory region (like eMMC, NOR).

The above also seems like a valid use case, especially when one wants to
support device for a long time (many DTBs) and avoid uncontrolled grown
of final u-boot.img binary size (as this is now the case for TI).

I'd rather stress that the problem is that when we want to support N
boards and we do that by including N device tree blobs, the size is
going to grow with each board.  What's not happening yet is the DTB is
being stored in the device and accessed that way.  I'd really like to
see some boards moving in that direction.  And it seems like perhaps
you're working on some that could?  Thanks!

Yes the goal is to have a single binary that support multiple evms for a
given SoC family. Similar to what we are doing for OMAP devices except
using U-boot instead of SPL.

OK.  The point for here (and patch 28) is that I'd like to see the DTS
queued up in the appropriate tree for the kernel before we pull it in
here (or at least the maintainer saying they'll pull it when gathering
stuff next) so that we don't have them getting out of sync.  Thanks!

The problem I see is storing dtbs that U-boot needs as part of booting
at a different location requires alot of guarantees across all the evms
being supported by the single image. If for NAND boot one board stores
U-boot's dtb blobs in one partition vs another then things fall apart.
The larger this minimal dtb is the harder it is to guarantee that it
will be valid in the future when/if new boards are introduced or reved.

The benefit of having a dtb bundled in the U-boot image is that no
matter the boot mode or board differences as long as something loads
U-boot it can then select the proper dtb to use from memory. I think I
remember Andrew also saying how having U-boot's dtbs built in will make
things easier in the HS world.

Now the method that U-boot is loaded and where U-boot is stored will
need to deal with U-boots larger size. But I think its rather enviable
since atleast for TI evms we kept space allowance for U-boot in NOR and
NAND rather small for no real reason.

In general if someone adds support and makes use of using a minimal
U-boot dtb and loading the "correct" one from some other location I
wouldn't have an issue with that. But atleast to me I don't think that
is the direction for TI evms.
