These two should be put above syscon.h if you want to keep the includes
sorted alphabetically.

Technically logo is const.


All the best

int bmp_display(ulong addr, int x, int y);
And throughout the code, I only find ulong parameters being passed to
this function.
Perhaps I can replace "logo" with "addr".

Thanks and regards,

I'm afraid my comment was perhaps too terse: I wanted to point out that
your "ulong logo" variable is assigned to only once, its value is never
changed, so instead of plain "ulong", you could declare its type as
"const ulong". I won't insist on this change since the code is trivial.

Consider simply removing the new variable and just passing
"(ulong)stmicroelectronics_uboot_logo_8bit_rle" directly as the
bmp_display()'s argument, like in
board/st/stm32f746-disco/stm32f746-disco.c.
