From 076c7f4c6c55c37975c8e04ae6827267794d5d2e Mon Sep 17 00:00:00 2001 From: Dmitry Baryshkov Date: Thu, 4 Sep 2008 13:28:33 +0400 Subject: [PATCH] [MTD] [NAND] tmio_nand: fix base address programming Fix offset of second word used for programming base address of memory window. Also program tmio with offset of the FCR, not with physical memory location.
