Hello Tom,
CI does show that no boards went oversize . If there is some growth on
existing devices, maybe we can shrink that, but maintaining obsolete DTC
code base going forward and picking random updates into it, that will only
lead to increasing maintenance pain, so I don't want to do that.
Yeah, it's not an easy spot. But I'm really not happy with growing main
U-Boot almost everywhere by 2KiB - 4KiB, and SPL by ~512 bytes or more
just to keep up. I do see that integratorcp_cm1136 barely grows at all,
so maybe there's something that can be done more widely and just wasn't
clear at first. m68k only grows an average of 500 bytes and MIPS is
~1KiB. PowerPC grows a lot. RISC-V a little.
I suspect this might have to do with DTO support. The imx8mp_dhcom do
use DTOs and the fdt_overlay.c code grew a lot.
I also found out that if I patch out can_assume() and replace it with
plain 1 , then the size drops by 1-2 kiB, but that's probably not what
we want to do.
