[Buildroot] [PATCH v7 0/3] add support for TI's AM64x boards

[Buildroot] [PATCH v7 0/3] add support for TI's AM64x boards

[Anand Gadiyar via buildroot]

This series introduces support for TI's AM64x SK boards.

We would like to add support for the AM62x SK as well, but are
currently blocked by availability of some firmware. That's still
on the list, as is the SK-TDA4VM. We should also be able to
enable the beagleboard-ai64 alongside that at the same time.


This series was previously sent out by Xuanhao in August and
was reviewed by Giulio Benetti up to v5 (Thanks!).

This series addresses further review comments for v5 from Romain
Naour and for v6 from François Perrad. Thanks for the reviews
Romain and François!

Andrew Davis acked the previous series, except for one new change
that I've addressed in this version.

I addressed all of Romain's comments except one - I couldn't get
the sha256sum for the k3-image-gen package to be updated in the
source repository, so for now it's still manually computed. I'll
see what I can do about getting the repository owners to generate
these automatically at release time.

Changes in v7:
- changes per François Perrad's review comments

Changes in v6:
- rebased to latest next branch and retested
- updated u-boot and kernel to latest released versions as of today
From Andrew's comments:
- added a new SOC_TYPE option for k3-image-gen, as requested by Andrew
  Davis in a review comment.
From Romain's comments:
- use "if" instead of "depends on" for sub-options
- move TI K3 R5 Loader defconfig selection to Kconfig
- use $(HOST_DIR) instead of $(HOST_ARM_GNU_TOOLCHAIN_INSTALL_DIR)
- Retain Xuanhao's gmail ID in the MAINTAINERs file, but drop his TI
  email from CC list as it will be inactive till he rejoins TI
- Add a plain-text license file into the k3-image-gen repository and use
  it instead of the HTML manifest file. Confirmed that this is still
  BSD-3-Clause license.
- Add comments in the ti-k3-image-gen.mk file for a couple of options

Changes in v5:
- None (resubmission of Xuanhao's series)

Changes in v4:
- rebased to latest master and retested
- dropped OPTEE CUSTOM* options as we don't need them.

Changes in v3:
- Fix boot/ti-k3-r5-loader package's build options and dependencies.
- Fix boot/ti-k3-image-gen package's config
- Add more details in board/ti/am64x_sk's readme
- Trim configs/am64x_sk's toolchain options and 
  fix uboot and genimage dependencies.
- Remove board/ti/am62x_sk and configs/am62x_sk for now due to some
  firmware dependency problems. Will be added back in the future.

Changes in v2:
- Revert arm-gnu-toolchain back to version 10.x due to a bug.
  When the pre-packaged GCC was built, it could be targeting
  a newer x86_64 architecture than the processor being used.
- Add boot/ti-k3-r5-loader package that builds a separate U-Boot
  for the R5 cores on TI's K3 devices.
- Add boot/ti-k3-image-gen package that builds the full boot binary
  tiboot3.bin from the spl built from ti-k3-r5-loader.
- Add board/ti directory to include sdcard config and board information
  for AM64x_sk and AM62x_sk boards.
- Add the Buildroot defconfigs for AM64x_sk and AM62x_sk.
- Add to DEVELOPERS list.

[Buildroot] [PATCH v7 1/3] boot/ti-k3-r5-loader: add new package

[Anand Gadiyar via buildroot]

From: Xuanhao Shi <x-shi@ti.com>

This is a separate U-Boot package that would build
the intermediate spl binary for the R5 core on TI's k3 boards.
Usually, the resulting spl will be used for k3-image-gen
to build the full R5 boot binary tiboot3.bin.

+Texas Instuments AM64x SK Test and Development Board
+
+Description
+===========
+
+These configurations will build a complete image and
+device tree blobs for the the TI AM64x_sk board.
+
+How to build it
+===============
+
+Select the default configuration for the target:
+$ make am64x_sk_defconfig
+
+Optional: modify the configuration:
+$ make menuconfig
+
+Build:
+$ make
+
+Result of the build:
+===================
+output/images/
++-- soc
++-- ti-connectivity
++-- bl31.bin
++-- boot.vfat
++-- Image
++-- k3-am642-sk.dtb
++-- r5-u-boot-spl.bin
++-- rootfs.ext2
++-- rootfs.ext4
++-- rootfs.tar
++-- sdcard.img
++-- tee.bin
++-- tee-header_v2.bin
++-- tee-pageable_v2.bin
++-- tee-pager_v2.bin
++-- tiboot3.bin
++-- tispl.bin
++-- u-boot.img
+
+To copy the image file to the sdcard use dd:
+$ dd if=output/images/sdcard.img of=/dev/sdX
+
+Insert the SDcard into the AM64x_sk board, and power it up with
+a USB Type-C connector. The system should come up. You can use
+a micro-USB to connect to the connector labled MAIN_UART0 to
+communicate with the board.

Simplified to just "Configuration".

You didn't test the build, as this hash file doesn't match the .mk
file: the .mk file refers to 2022.10, the hash file to 2022.10-rc1.

Another thing: the hash of the license file was missing.

I fixed up those small issues, and applied. Thanks!

The commit title should just be:

Download SUCCESS!

This is not acceptable as it circumvents the download infrastructure of
Buildroot, but also the legal information collection infrastructure.

This needs to be fixed by downloading this file, either through a
separate package, or as an _EXTRA_DOWNLOADS of this package, and the
Makefile needs to be changed to not download this file. My impression
is that the Makefile will not download the files if they are already
available. So you could have _EXTRA_DOWNLOADS + some post-extract logic
to put the files at the right place.

Best regards,

Thomas

Please use some better wording:

This commit adds a new defconfig that allows to build a minimal
Buildroot system for the A64x_sk board, which is based on the TI AM642
SoC, featuring ....

These configurations => This configuration

No need to have "and device tree blobs", this is implied by "complete
image".

Could you make the OP-TEE version explicit, so that we build a
known-working version?

Thanks, but it needs to be integrated in a v8 of the patch series.

Thanks for the comments Thomas and I apologize for not
catching these points earlier. We did build but didn't read the
log messages obviously.

I will rework and resubmit v8 shortly.

Why putting the version in the Config.in? Buildroot package usually 
don't
include the version here. It may be missed later, when the package is
updated. Is there anything special about this version?
If not, consider removing the version here.

Comment says: Options are "gp", "hs-fs", or "hs-se".

If those are the only choices, why not using a Kconfig "choice" instead?

Moreover, when trying with a SK-AM64B board, I needed to set "hs-fs" 
(because B board
seems to include a Silicon Revision 2.0, which requires "hs-fs"). In 
that case,
compilation failed with:

ti-k3-image-gen 08.05.00.004 Building
Makefile:67: *** TI_SECURE_DEV_PKG must be set for HS, defaults will not 
work.  Stop.

This "hs-fs" seems to be broken, for now.

A note could be added here, about the meaning of "gp" (General Purpose), 
and
"hs-fs" High-Security Field Securable and how it is linked to some 
silicon revision.
Ex:
https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1158018/faq-processor-sdk-am64x-am64x-am243x-sr-2-0-device-type-transition

The empty line at end of Config.in file generate "make check-package" 
warning:

...
1 warnings generated

There is a newer version 08.05.00.007 available. See:
https://git.ti.com/cgit/k3-image-gen/k3-image-gen/tag/?h=08.05.00.007
Consider taking the latest version in the next patch version, unless 
there is a
specific reason for taking the proposed one (in that case, please add a 
comment).

To avoid confusion between SK-AM64 and SK-AM64B, I suggest:

1. to add the board url in this readme.txt, for example,
using the same comment as in the commit log:
"""
More information about the board can be found at:
https://www.ti.com/tool/SK-AM64
"""

2. add a note that:
This configuration is for SK-AM64 only, since it's including:
BR2_TARGET_TI_K3_IMAGE_GEN_SOC_TYPE="gp"
The SK-AM64B [2] is not supported, as it would require "hs-fs".

Thanks for the review Julien!

The SK-AM64B wasn't around when we submitted the first patchset.
I expected a follow on patch to add the hs-fs support properly.

I'll clarify in the next revision that this series is for GP only. We'll need
some work to get the SK-AM64B supported and tested, and I'll try and
get that enabled after this initial series is merged.

I'll post a new series shortly with changes addressing review comments
from you and Thomas

Hi Patrick,

I gave up after the last round of review comments, but there is someone
at TI who has taken it up again recently.

They're focusing on the AM62x including other goodies like display and GPU, and
has a working baseline. He was planning to post the series upstream shortly after.

The series 7 should still work functionally. All the review comments were
valid though and might be easy to address if you want to start from there.

Since there is community interest in having AM64x support, I would love to
take this up again.

Best Regards,
Anand

I work for TI and have since picked up the work on the v7 patch series
that Anand and others last worked on. I've been forward porting the
exisiting patches on top of the latest 'master' commit, doing some
further cleanup also considering v7 feedback, plus making enhancements
needed to better support TI K3 SoCs. I've also added AM62x support, and
currently working on adding GPU support for AM62x (I have it already
working being able to run Weston and Chocolate Doom for testing
purposes, just needs some more cleanup).

My intermediate work is posted here [1] together with some instructions
and how to get it to work for anybody interested in the full solution
*today*.

My plan is once GPU support is complete and cleaned up I'll post a v8
series to this mailing list here with everything in it, and work with
the community on any further cleanup that may be needed. I expect to be
able to start this process next week. So I'd appreciate if we can
refrain from posting additional TI K3 patches until then.

Once merged, the temporary page [1] will get updated and/or dismantled.
It is certainly not meant to be a "forked solution" of sorts, and was
only intended to be a stop-gap measure for some immediate customer needs
we had here at TI.

Thanks,

Thanks. I was able to get the PHYTEC board working using your patches
as a starting point.
