Ah yes, I think I know the issue..
Angler's firmware (probably Huawei's job, but unsure) seems to make IOMMUs (another guesstimate)
not report where the memory is allocated. If it's an issue only on these boards, I reckon
it would be better to just add
"/delete-node/ &cont_splash_mem;"
in angler/bullhead DTSI, as other 8992/4 devices seem to not have this issue. But as I've said, bullhead could
probably work anyway, but if it doesn't, it's probably Google's job after all..
P.S
I did not suggest redefining the node, as the memory@0 is reserved for SoC registers
and your firmware is just playing tricks on you. Your RAM starts @ 0x80000000.
