# This is far from simple, but I couldn't think of a good name. This is # for making the 'zImage' or 'zImage.initrd' on a number of targets. # # Author: Tom Rini # # 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.
