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(). > And of course the debugging information is included in the commit log so > that others can see what problem you're experiencing and make a decision > whether the proposed solution is the right one... Yeah, why not, I will add it in next version. Thanks. - Kukjin
