From c478d7e449508d924628b012e62dee6dddb6b9e9 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Tue, 28 Jun 2011 16:29:00 -0700 Subject: [PATCH] mtd: edit NAND-related comment This comment was unclear regarding which NAND functions do and do not support ECC on the spare area. This update should reflect the current status of the NAND system but can be updated if changes are made in the standard functions.
