[POWERPC] cuimage for Bamboo board
Add a cuboot wrapper for the Bamboo board. Additionally, we enable MAC address fixups for both cuboot and treeboot. This also removes some obsoleted linker declarations that have been moved into ops.h Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com> Acked-by: David Gibson <david@gibson.dropbear.id.au>
