Trying to figure out how I should map the MMU for normal RAM so it acessible
from all ELx security states.
So far I have this mem_map:
/* memory mapped RAM. 32MB */
.virt = 0x60000000UL,
.phys = 0x60000000UL,
.size = 0x02000000UL,
.attrs = PTE_BLOCK_MEMTYPE(MT_NORMAL) | PTE_BLOCK_INNER_SHARE
but starting to doubt that is correct, can someone suggest what to put in the .attrs field?
