From fd508da2208696db146cd1be2bb2e8b799f6e3a2 Mon Sep 17 00:00:00 2001 From: Barry Song Date: Thu, 5 Aug 2010 11:07:42 -0400 Subject: mtd: Blackfin NFC: make sure to check NAND_ALE in cmd_ctrl The NAND base may send some controls which are neither CLE nor ALE, so we need to explicitly check both instead of assuming things are always one or the other. Otherwise, we sometimes send out illegal addresses to the NAND device.
