[PATCH] ppc32: cleanup AMCC PPC40x eval boards to support U-Boot
Cleanup PPC40x eval boards (bubinga, walnut and sycamore) to support U-Boot as bootloader. The OpenBIOS bd_info struct is not used in the kernel anymore (only U-Boot now). uImage (U-Boot) tested on walnut, sycamore and bubinga zImage (OpenBIOS) tested on sycamore, bubinga and ebony Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Matt Porter <mporter@kernel.crashing.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
