Benjamin Herrenschmidt 6879dc137e [PATCH] ppc32: Kill embedded system.map, use kallsyms
This patch kills the whole embedded System.map mecanism and the
bootloader-passed System.map that was used to provide symbol resolution in
xmon.  Instead, xmon now uses kallsyms like ppc64 does.

No hurry getting that in Linus tree, let it be tested in -mm for a while
first and make sure it doesn't break various embedded configs.

# 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.
