Add Rockchip u-boot "binman" BOOT_SCENARIO

[brentr]

Description

Added a new "binman" BOOT_SCENARIO to allow other Rockchip boards to use 2024.10 with without resorting to defining custom write_uboot_platform() in each board config.
Update RockPI-S and Rock S0 from u-boot v2022.04 to u-boot v2024.10 to use the new "binman" BOOT_SCENARIO as an example.

It's my hope that other Rockchip board maintainers who are using u-boot's new binman single file boot image will take advantage of this to simplify their board configs.

This pull request replaces the closed, stale PR #7486

Documentation summary for feature / change

• Implement new "binman" BOOT_SCENARIO in families/include/rockchip64_common.inc
• Update Rock S0 and RockPI-S to use current u-boot (v2024.10) with this new scenario

How Has This Been Tested?

• Generated and tested edge (6.12) and current kernel based images for both boards
• Verified that new v2024.10 u-boot SPL can boot from both EMMC and SD cards

Please test this fresh PR instead of (closed, stale) #7486
(before someone else decides to muck about in rockchip64_common.inc :-)

Hey @brentr, git push --force to forked PR branches are a thing, no need to recycle PR otherwise we lose the discussion context.

But since you squashed and split I'm gonna go nit:

• Take this as an opportunity to move the blobs to armbian/rkbin, with all the others. armbian/build is already a monster git fetch. PRs to armbian/rkbin are usually merged pretty fast
• Split the commit into the one the PR title is about, and 2 others for the boards in question.
• Use bash lib/tools/shellfmt.sh to fix whitespace issues in the 2 board files, commit, then optionally squash into the board commits
• force push & re-request review

[rpardini]

btw, by moving the blobs to the correct repo you can get rid of the RKBIN_DIR acrobatics.

I hope this will include the configurations for other rockchip SoCs as well, such as rk356x and others. Will make adding new rockchip boards easier and help keep other rockchip boards up to date.

Great opportunity for you to test; the way I see this, for a board currently using hooks to do the binman stunt, moving the vars from hook to globals, removing the hooks, and setting BOOT_SCENARIO=binman should just work for the sd/emmc scenario. For SPI there's more work needed, and we should upgrade write_mtd to use flashcp as most of the board hooks do.

@rpardini
I have created
armbian/rkbin#32
with the rk3308 blobs.
If you need to build rock-S0 or rockPI-S before that PR is merged, point compile.h at my fork of rkbin:

export RKBIN_GIT_BRANCH=addBootScenarioForRockchip
export RKBIN_GIT_URL=https://github.com/brentr/rkbin

(Since the tools in armbian/rkbin are 7 years out of date, I honestly thought the armbian clone was obsolete. I guess it's just become a dumping ground for blobs built with the tools in rockchip-linux/rkbin.)

@rpardini
"git push --force to forked PR branches" may, indeed, be "a thing"
But, I've never done it before. I was unsure how to go about it without losing history.
If you could point me at a good tutorial, I'll try it next time a PR of mine goes stale.

[brentr]

@rpardini
I really do not want to break this into multiple PRs.
The two altered board config files are dependent on the new BOOT_SCENARIO.

I've done everything else on your punch list.

[rpardini]

I have created armbian/rkbin#32 with the rk3308 blobs.

Merged. Thanks. It is indeed a dumping ground for rk stuff; the main point being that not everyone who fetches armbian/build will need rkbins, and those are fetched on-demand anyway.

I really do not want to break this multiple PRs.

• Split the commit

Multiple PR's != multiple commits in a single PR.

In the end of the day, what will survive history here is what is in git (commits), not GitHub PR's.

But really, it's fine for now -- see below, as you gain experience with git rebases those become simpler.

I was unsure how to go about it without losing history.

Hmm, rebases (and force-pushes) are essentially about rewriting history, in a controlled manner. See https://git-scm.com/book/en/v2/Git-Branching-Rebasing

I've done everything else on your punch list.

Excellent. Thanks. I shall pick and test again.

Multiple PR's != multiple commits in a single PR.

I misunderstood. In future, I'll take more care to split commits.

[rpardini]

I've done everything else on your punch list.

rockchip64_common.inc is also full of whitespace inconsistencies. shellfmt

You forgot this.

---

I took the liberty then to pick, test, fix a few unrelated newline/whitespace changes, squash the blob removals out, and split the commits. I've pushed to your branch.

I've also fired a build of all u-boots, some 600+, I'll post the links to GHA when they're done. That way we can be confident the stuff still builds fine. Thus far it's looking good.

@rpardini
Good to hear that the tests are working.

How wide is your screen?
I grew up editing on Lear Siegler and similar terminals:
https://en.wikipedia.org/wiki/ADM-3A
and (gasp) printing source code!

The legacy of those years is a firm belief that lines longer than 100 chars should be avoided.

[rpardini]

not relevant here, discuss newline policy in a separate thread.
since you were changing unrelated comments by adding line breaks, I "fixed" it for you.

[rpardini]

All built fine. Part 1 and Part 2 -- failed builds are either my own userpatched things/crap or had already been broken before.

Please review my changes and merge at will.

[rpardini]

Heh, you squashed when you merged. Oh well.

[JohnTheCoolingFan]

So much for preserving history lol. Although I wish git had some sort of "tagging" commit ranges, or un-squashing a squashed PR, although that would complicate things a lot.

[rpardini]

We won't force-push to main unless something catastrophic happened, which it didn't, so let's move on.
