RE: Lots of memory on 826x

I can use 1GB of RAM now, if I move kernel base to 0xA0000000 and set=20
lowmem size to 1GB. (No Highmem at all)

Ahh, but early ioremaps (before mm is inited) grow down from=20
PKMAP_BASE,
so you will be overlapping the top of lowmem with those allocations.
It wants to be above vmalloc space.  Set HIGHMEM_START to 0xF6000000,
IMMR/IO to 0xF8000000 and you then have vmalloc space between
0xF1000000-0xF5FFFFFF.

I'll try this tomorrow and see what happens.=20
(Still need to make sure our board supports 2GB....:)
