From a40f73419f02e40555f692785ea1c1813d5b4c12 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Tue, 31 May 2011 16:31:22 -0700 Subject: mtd: nand: consolidate redundant flash-based BBT flags This patch works with the following three flags from two headers (nand.h and bbm.h): (1) NAND_USE_FLASH_BBT (nand.h) (2) NAND_USE_FLASH_BBT_NO_OOB (nand.h) (3) NAND_BBT_NO_OOB (bbm.h) These flags are all related and interdependent, yet they were in different headers. Flag (2) is simply the combination of (1) and (3) and can be eliminated. This patch accomplishes the following: * eliminate NAND_USE_FLASH_BBT_NO_OOB (i.e., flag (2)) * move NAND_USE_FLASH_BBT (i.e., flag (1)) to bbm.h It's important to note that because (1) and (3) are now both found in bbm.h, they should NOT be used in the "nand_chip.options" field. I removed a small section from the mtdnand DocBook because it referes to NAND_USE_FLASH_BBT in nand.h, which has been moved to bbm.h.

This patch enable this feature. Update platform driver to support this feature. Another notice should be taken that: When you want to use this feature, you should not enable the keep configuration feature, for two chip select could be attached with different nand chip. The different page size and timing requirement make the keep configuration impossible.
