[U-Boot-Users] [PATCH] fix the ARM memory layout

[Anders Larsen]

Hi,

here's a fresh version of my rather intrusive patch from the 17.th sept.
to rearrange the ARM memory layout to bring it in line with the README.

This has the positive side-effect of actually allow U-Boot to run on
PXA- and IXP-based targets; the current implementation sets up the heap
using bogus addresses causing u-boot to crash (this even applies to the
recently added board "ixdp425").

This patch doesn't go all the way, though, since doing away with the
board-specific setting of TEXT_BASE would require the code to be
position-independent, which at least the cpu initialization code in
cpu/*/start.S is _not_.

CHANGELOG:
   Bring the ARM memory layout in line with the documentation.

Cheers
 Anders
