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>

# Makefile for making ELF bootable images for booting on CHRP
|
|
# using Open Firmware.
|
|
#
|
|
# Geert Uytterhoeven September 1997
|
|
#
|
|
# Based on coffboot by Paul Mackerras
|
|
# Simplified for ppc64 by Todd Inglett
|
|
#
|
|
# NOTE: this code is built for 32 bit in ELF32 format even though
|
|
# it packages a 64 bit kernel. We do this to simplify the
|
|
# bootloader and increase compatibility with OpenFirmware.
|
|
#
|
|
# To this end we need to define BOOTCC, etc, as the tools
|
|
# needed to build the 32 bit image. That's normally the same
|
|
# compiler for the rest of the kernel, with the -m32 flag added.
|
|
# To make it easier to setup a cross compiler,
|
|
# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
|
|
# in the toplevel makefile.
