From 82b95ecb96122896fd5b7b75001fdda3e047ef38 Mon Sep 17 00:00:00 2001 From: Haojian Zhuang Date: Thu, 10 Sep 2009 13:55:23 +0800 Subject: pxa3xx_nand: move pxa3xx_nand.h common into plat directory Since the same nand controller is shared between ARCH_PXA and ARCH_MMP. Move the pxa3xx_nand.h from mach directory to plat directoy.
