        Classification: 




Made the patch specific to a board/cpu combination as suggested by Peter 
Pears. 

Starting U-boot directly from the flash on the ARM integrator ommitted
setting of the Core Module control register flag that remaps SSRAM to the
base memory address 0x0000000. The problem surfaces when the ARM core
(920T in my case) is mounted on a motherboard.(Integrator AP) and the
bootloader started from flash. Starting the bootloader from the ARM
debugger does not reveal this problem. It automatically sets this bit by
default and explains why some people did not see the problem.

Added documentation to the README file that describes that the options 
CONFIG_CM9x0, CONFIG_INTEGRATOR and CFG_INTEGRATOR_CM_REMAP should be 
defined to turn this behaviour on.
