1# This is far from simple, but I couldn't think of a good name. This is
2# for making the 'zImage' or 'zImage.initrd' on a number of targets.
3#
4# Author: Tom Rini <trini@mvista.com>
5#
6# Notes:
7# (1) For machines that do not want to use the ELF image directly (including
8# stripping just the ELF header off), they must set the variables
9# zimage-$(CONFIG_MACHINE) and zimagerd-$(CONFIG_MACHINE) to the target
10# that produces the desired image and they must set end-$(CONFIG_MACHINE)
11# to what will be suffixed to the image filename.
12# (2) Regardless of (1), to have the resulting image be something other
13# than 'zImage.elf', set end-$(CONFIG_MACHINE) to be the suffix used for
14# the zImage, znetboot, and znetbootrd targets.
15# (3) For machine targets which use the mktree program, you can optionally
16# set entrypoint-$(CONFIG_MACHINE) to the location which the image should be
17# loaded at. The optimal setting for entrypoint-$(CONFIG_MACHINE) is the link
18# address.
19# (4) It is advisable to pass in the memory size using BI_MEMSIZE and
20# get_mem_size(), which is memory controller dependent. Add in the correct
21# XXX_memory.o file for this to work, as well as editing the
22# misc-$(CONFIG_MACHINE) variable.
