[PATCH v4 0/3] Add Onion Omega2/2+ board support

[Philip Oberfichtner]

Add support for the MediaTek based boards by Onion. Commit one and two are
rather generic, whereas the third commit adds the actual board support.

Changes in v4:
	- Rebase board support to v2025.07
	- Add new commit to silence warning in arch/mips/

Changes in v3:
	- Simplify image size check

Changes in v2:
	- I forgot to run checkpatch in v1. Fix some style issues in v2.

[PATCH v4 1/3] Makefile: Add size check for u-boot-with-spl.bin

[Philip Oberfichtner]

Like other images, u-boot-with-spl.bin may be subject to size
restrictions. Extend CONFIG_SPL_SIZE_LIMIT to handle this case.

There's a rule in the Makefile
ifneq ($(CONFIG_SPL_SIZE_LIMIT),0x0)
SPL_SIZE_CHECK = @$(call size_check,$@,$$(tools/spl_size_limit))
else
SPL_SIZE_CHECK =
endif

and

isn't this running?

Well, before this patch it only ran for the u-boot-spl.bin target. But I
also need it for the combined u-boot-with-spl.bin image.

I'm not sure if this answers your question?


Just for reference I'll put a link to the previous discussion with Tom:

This is not quite right enough, sorry. This causes a number of boards
(evb-ast2600 ibm-sbp1 stm32746g-eval_spl stm32f746-disco_spl
stm32f769-disco_spl) which have size checks and are fine to now fail
their size checks, presumably because they're checking the "wrong" file
now or similar. So if you can't see a way to fix both them and your
board then sigh, I was wrong initially and we will need another size
check method like you proposed to start with.

Thanks for pointing that out. To sum it up: If those boards use
SPL_SIZE_LIMIT to restrict the size of an SPL-only image, then
u-boot-with-spl.bin, of course, can be too large and the build fails.

Plus in our previous discussion, we figured out why using
BOARD_SIZE_LIMIT also isn't suitable:
https://lore.kernel.org/u-boot/aD2EflR9DRYG-MY5@antares/

So from here I really don't see any better way than introducing yet
another CONFIG_*SIZE_LIMIT option.


But maybe we can however simplify and deduplicate some of the code. What
do you think about something like that (I have not yet tested it, just
a rough idea so far):

That sounds like a good idea, so long as it works :) Thanks!

So I've tested it for multiple board/image combinations. Should be fine
now. v5 is on the way.

[PATCH v4 2/3] mips: serial: Silence "unused variable" warning

[Philip Oberfichtner]

Before this commit, mtmips_spl_serial_init() caused the following
warning:

  arch/mips/mach-mtmips/mt7628/serial.c:14:23: warning: unused variable ‘base’ [-Wunused-variable]
     14 |         void __iomem *base = ioremap_nocache(SYSCTL_BASE, SYSCTL_SIZE);
        |                       ^~~~

This happens whenever CONFIG_SPECIFY_CONSOLE_INDEX is unset, which leads
to an effectively empty function:

  void mtmips_spl_serial_init(void)
  {
	  void __iomem *base = ioremap_nocache(SYSCTL_BASE, SYSCTL_SIZE);
  }

Add the __maybe_unused attribute to silence this warning.
