This patch adds cuboot support for MPC7448HPC2 platform. The cuImage can be used with legacy u-boot without FDT support. Signed-off-by: Roy Zang <tie-fei.zang@freescale.com> Acked-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

# 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.
