This is +# for making the 'zImage' or 'zImage.initrd' on a number of targets. +# +# Author: Tom Rini <trini@mvista.com> +# +# Notes: +# (1) For machines that do not want to use the ELF image directly (including +# stripping just the ELF header off), they must set the variables +# zimage-$(CONFIG_MACHINE) and zimagerd-$(CONFIG_MACHINE) to the target +# that produces the desired image and they must set end-$(CONFIG_MACHINE) +# to what will be suffixed to the image filename. +# (2) Regardless of (1), to have the resulting image be something other +# than 'zImage.elf', set end-$(CONFIG_MACHINE) to be the suffix used for +# the zImage, znetboot, and znetbootrd targets. +# (3) For machine targets which use the mktree program, you can optionally +# set entrypoint-$(CONFIG_MACHINE) to the location which the image should be +# loaded at. The optimal setting for entrypoint-$(CONFIG_MACHINE) is the link +# address. +# (4) It is advisable to pass in the memory size using BI_MEMSIZE and +# get_mem_size(), which is memory controller dependent. Add in the correct +# XXX_memory.o file for this to work, as well as editing the +# misc-$(CONFIG_MACHINE) variable. + +boot := arch/ppc/boot +common := $(boot)/common +utils := $(boot)/utils +bootlib := $(boot)/lib +images := $(boot)/images +of1275 := $(boot)/of1275 +tftpboot := /tftpboot + +# Normally, we use the 'misc.c' file for decompress_kernel and +# whatnot.
