Hi
This patch is breaking the STM32MP15 basic boot (spl => u-boot).
Looking at socfpga gen5 u-boot.img, this is probably broken as well.
And I don't even see any RB or TB tags here :-(
Ugh, what the heck? I applied this because I looked over the changes
and they seemed correct. I'm quite willing to just revert this but I
would like to know how it's breaking. Sorry all!
IMHO this is due to wrong images creation with mkinage, especially when
passing parameters with -a and -e flags.
In my case I need them to be:
-a 0x80002000 (load address) => CONFIG_SYS_TEXT_BASE
-e 0x800023FD (entry point where SPL jumps to) => CONFIG_SYS_UBOOT_START
Well, CONFIG_SYS_UBOOT_START is only set in 15 files in include/configs, so I
guess a lot more boards might be broken...
So *maybe* on STM32MP1 and other broken boards -e
(CONFIG_SYS_UBOOT_START) is not equal to -a (CONFIG_SYS_TEXT_BASE) as
was assumed before(but wrong).
Indeed CONFIG_SYS_UBOOT_START is set to 0 if not specified in
u-boot/Makefile:
`
# U-Boot entry point, needed for booting of full-blown U-Boot
# from the SPL U-Boot version.
#
ifndef CONFIG_SYS_UBOOT_START
CONFIG_SYS_UBOOT_START := 0
endif
`
So probably broken boards try to jump to absolute 0.
A solving patch would be:
ifndef CONFIG_SYS_UBOOT_START
CONFIG_SYS_UBOOT_START := CONFIG_SYS_TEXT_BASE
endif
That might work, but I wonder if this is the correct time in the release to do
so.
Yes, at this point in the cycle the best option is to revert the
original commit and for the next release bring it back after applying
Patrice's series to fix the bogus default to CONFIG_SYS_UBOOT_START and
cleaning up defconfigs. Sorry again for all the troubles!
I just wanted to confirm socfpga_gen5 doesn't boot with this patch
but it's ok again now you reverted it.
Now that patches:
https://patchwork.ozlabs.org/patch/1205064/
https://patchwork.ozlabs.org/patch/1205063/
and 2020.01 has been released, can you please commit this patch?
I've re-submitted also on patchset to Add i.MXRT family since it's
needed to boot Linux:

Kind regards
