[U-Boot] [PATCH] spl: fix entry_point equal to load_addr

[U-Boot] [PATCH] spl: fix entry_point equal to load_addr

[Giulio Benetti]

At the moment entry_point is set to image_get_load(header) that sets it
to "load address" instead of "entry point", assuming entry_point is
equal to load_addr, but it's not true. Then load_addr is set to
"entry_point - header_size", but this is wrong too since load_addr is
not an entry point.

So use image_get_ep() for entry_point assignment and image_get_load()
for load_addr assignment.

Applied to u-boot/master, thanks!

[U-Boot] [PATCH] spl: fix entry_point equal to load_addr

[Patrice CHOTARD]

Hi

This patch is breaking the STM32MP15 basic boot (spl => u-boot).

I will send a fix proposal.

Thanks

Patrice

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!

Looking at the branch a few lines up I can understand why this seemed
like a small change. I hadn't seen this before Patrice's mail, either.

Let me test this on socfpga_socrates tomorrow, I could still be wrong since
this is from reading the code and binary only. But entry_point should be 0
in my u-boot.img if I'm not mistaken, and that should break it.

Regards,
Simon

Maybe I just haven't had enough coffee or time to think, but that sounds
like entry_point being set wrong somewhere.  Of course, if it's being
set wrong somewhere and it's not self-contained within U-Boot to correct
it (iow external scripts/docs), we have to deal with that reality.

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

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

What do you think?

Sorry for this mess!

Best regards

This is what i implemented to fix this issue. Here is my proposal [1], but i need some

feedback from some boards maintainers.

Well, CONFIG_SYS_UBOOT_START is only set in 15 files in include/configs, so I
guess a lot more boards might be broken...

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:
https://patchwork.ozlabs.org/project/uboot/list/?series=152468

Kind regards
