From b4f7aa84d6ff44327ab91a2973ebf0c2a7797d24 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Mon, 30 Apr 2012 19:30:47 +0200 Subject: mtd: add read_byte support to plat_nand Lantiq SoCs have a External Bus Unit (EBU) that is used to attach MTD media. As we need to co-exist with PCI on the same bus, certain swapping settings must be applied. Similar to the NOR map driver we need to apply a fix to make NAND work. The easiest way is to use byte reads.
