The board has 8MByte SDRAM and 8MByte Flash.=20 I have ported u-boot, modified Linux to add a new board config and added = the board specific definitions in arch/ppc/platforms.=20 U-Boot and Linux were built using the ppc_8xx compiler from ELDK 3.0. When I boot Linux I get the following:- ## Booting image at 00100000 ...
