When building a ppc32 MULTIPLATFORM kernel for a 64bit pmac, we try and build certain files or use certain functions that make no sense in that context. This catches the last of these.

# 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 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.
