From 262ae0a6193f10b6a94e86d2f752e7f5510416fa Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Thu, 3 Sep 2009 23:12:47 -0400 Subject: [PATCH] push LOAD_ADDR out to arch mk files Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in the standalone Makefile, push the setting up of LOAD_ADDR out to the arch config.mk (and rename to STANDALONE_LOAD_ADDR in the process). This keeps the common code clean and lets the arch do whatever crazy crap it wants in its own area.
