Display the STMicroelectronics logo with features VIDEO_LOGO and
SPLASH_SCREEN on STMicroelectronics boards.

2.25.1
I downloaded the patch from Patchwork, but when I apply it (git am
board-stm32mp1-add-splash-screen-with-stmicroelectronics-logo.patch),
the file tools/logos/st.bmp is empty, and the compilation fails.
I'm sorry for the stupid question, but what am I doing wrong?
Thanks and regards,
Dario
Hi Dario
I applied this patch on v2023.07 U-Boot tags and everything works fine, no
compilation errors and the logo is displayed as described in Patrick's patch.
I run the next commands:
$ git checkout -b 2023.07 v2023.07
$ git am ~/Downloads/board-stm32mp1-add-splash-screen-with-stmicroelectronics-logo.patch
...
The tools/logos/st.bmp is not empty, its size is 18244 bytes.
$ file tools/logos/st.bmp
tools/logos/st.bmp: empty
Hi Dario
I found the reason why we got different behavior.
In my side i retrieved the patch from my mailer (Thunderbird) and not
from patchwork as you did.
I confirm, from patchwork i get the same issue as yours, there is an
issue with binary part of the patch => st.bmp file
When part of the patch include binary, we should use --binary option 
which was not the case when Patrick generated this patch.
I will resubmit the patch with correct option.
I generate again this patch using --binary and full-index options, i submitted it
to the mailing list but unfortunately, the issue is the same.
It seems that patchwork can't handle correctly patch included binary parts.
Please find attached the patch to try in your side

Thanks for pointing this issue.

Can you show the compilation error you get ?
