From b8f80684054ec8a3bcdf35dc9c76ddf629a36482 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Tue, 31 May 2011 16:31:24 -0700 Subject: mtd: nand: move NAND_CREATE_EMPTY_BBT flag The NAND_CREATE_EMPTY_BBT flag was added by commit: 453281a973c10bce941b240d1c654d536623b16b mtd: nand: introduce NAND_CREATE_EMPTY_BBT This flag is not used within the kernel and not explained well, so I took the liberty to edit its comments. Also, this is a BBT-related flag (and closely tied with NAND_BBT_CREATE) so I'm moving it to bbm.h next to NAND_BBT_CREATE, thus requiring that we use the flag in nand_chip.bbt_options, *not* in nand_chip.options.
