# 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 <trini@mvista.com>
#
# Notes:
# (1) For machine targets which produce more than one image, define
# ZNETBOOT and ZNETBOOTRD to the image which should be available for
# 'znetboot' and 'znetboot.initrd`
# (2) Also, for machine targets which just need to remove the ELF header,
# define END to be the machine name you want in the image.
# (3) For machine targets which use the mktree program, define END to be
# the machine name you want in the image, and you can optionally set
# ENTRYPOINT which the image should be loaded at. The optimal setting
# for ENTRYPOINT 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) file.
