Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+# 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.
