Hi
in hal_platform_setup.h ( iq80310/include), i noticed that we are
enabling MMU and then scrubbing sdram starting from RAM_BASE i.e A0000000.
Now, my doubt is:
since we have mapped the first 4K of RAM to flash,
[ mmu_table_rambase:
// Map 4k page at 0xa0000000 virt --> 0x00000000 physical
// Read-Write, cacheable, non-bufferable ]
does that mean writing a 0x00 to a0000000 is same as writing to flash?
Am i missing something here?

Worry about chances you miss when you don't even try.
