From c135456ff59aed0302f99a2e1327939bdced77f5 Mon Sep 17 00:00:00 2001 From: Ben Gardiner Date: Tue, 14 Jun 2011 16:35:05 -0400 Subject: nand_util: treat WITH_YAFFS_OOB as a mode When specified in the flags argument of nand_write, WITH_YAFFS_OOB causes an operation which is mutually exclusive with the 'usual' way of writing. Add a check that client code does not specify WITH_YAFFS_OOB along with any other flags and add a comment indicating that the WITH_YAFFS_OOB flag should not be mixed with other flags.
