From a9b71a8f0f42efe1a21154667ca02305c950d30a Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Thu, 10 Nov 2011 12:06:21 +0000 Subject: [PATCH] MIPS: Alchemy: move au1200fb global functions to platform data au1200fb calls 3 functions which have to be defined in board code. Fix this ugliness with the introduction of platform_data.
