Yeah, correct. The size of memory bank should be under section size and
current section size is 256MiB on EXYNOS. So if we don't change the section
size, each memory bank should be under 256MiB. If not, as Tomasz said,
kernel panic happens in mem_init().

Yeah, why not, I will add it in next version.

Thanks.
