From 1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Sat, 16 Apr 2005 15:20:36 -0700 Subject: 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.

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. + +boot := arch/ppc/boot +common := $(boot)/common +utils := $(boot)/utils +bootlib := $(boot)/lib +images := $(boot)/images +of1275 := $(boot)/of1275 +tftpboot := /tftpboot + +# Normally, we use the 'misc.c' file for decompress_kernel and +# whatnot.
