From 6a08e1e6f7fafa2fa5fb6a129c4c8d9c29f11b62 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Wed, 25 Sep 2013 15:44:39 -0700 Subject: [PATCH] ARM: OMAP2+: Add quirk support for legacy platform data init We want to drop the board-*.c files but keep things working. Let's make it a bit easier to support legacy platform data init with quirks. This also keeps board-generic.c clean from board specific hacks. For now, the quirks table is empty, that is populated in the later patches.
