From 67a490d60d70f2b01d55976440ba30154af96965 Mon Sep 17 00:00:00 2001 From: michael Date: Mon, 14 Mar 2011 21:16:38 +0000 Subject: [PATCH] atmel_nand: don't require CONFIG_SYS_NAND_ENABLE_PIN If NCE is hooked up to NCS3, we don't need to (and can't) explicitly set the state of the NCE pin. Instead, the controller asserts it automatically as part of a command/data access. Only "CE don't care"-type NAND chips can be used in this manner.
