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

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
