* mtd: mpc5121_nfc: Fix module autoload for OF platform driverLuis de Bethencourt2015-09-291-0/+1

| | | | | | | | | | | | | | None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

* mtd: kill MTD_NAND_VERIFY_WRITEHuang Shijie2012-09-291-22/+0Star
| | | | | | | | | | | | | | | | Just as Artem suggested: "Both UBI and JFFS2 are able to read verify what they wrote already. There are also MTD tests which do this verification. So I think there is no reason to keep this in the NAND layer, let alone wasting RAM in the driver to support this feature. Besides, it does not work for sub-pages and many drivers have it broken. It hurts more than it provides benefits." So kill MTD_NAND_VERIFY_WRITE entirely.

* mtd: nand: rename NAND_USE_FLASH_BBTBrian Norris2011-09-111-1/+1
| | | | | | | | | | | | | | | Recall the recently added prefix requirements: * "NAND_" for flags in nand.h, used in nand_chip.options * "NAND_BBT_" for flags in bbm.h, used in nand_chip.bbt_options or in nand_bbt_descr.options Thus, I am changing NAND_USE_FLASH_BBT to NAND_BBT_USE_FLASH. Again, this flag is found in bbm.h and so should NOT be used in the "nand_chip.options" field.

* mtd: nand: consolidate redundant flash-based BBT flagsBrian Norris2011-09-111-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

NOTE! This merge commit was created to fix compilation error. The block tree was merged upstream and removed the 'elv_queue_empty()' function which the new 'mtdswap' driver is using. So a simple merge of the mtd tree with upstream does not compile. And the mtd tree has already be published, so re-basing it is not an option. To fix this unfortunate situation, I had to merge upstream into the mtd-2.6.git tree without committing, put the fixup patch on top of this, and then commit this. The result is that we do not have commits which do not compile. In other words, this merge commit "merges" 3 things: the MTD tree, the upstream tree, and the fixup patch.
