From e735aa8a20fdc60439141b7b0c0382a3ce031f3b Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 15 Feb 2010 09:27:25 -0800 Subject: [PATCH] omap2/3/4: Clean up entry-macro.s for adding support for omap4 multiboot Move defines around and set up handlers based on MULTI_OMAP2. Note that this will only allow compiling in omap4 with omap2 and omap3. It will not yet make omap4 boot with multi-omap.
