Currently atmel_nand driver used by AT91 and AVR32 calls a special callback which return nand partition table and number of partitions. However in all boards this callback returns just static data. So drop this callback and make atmel_nand use partition table provided statically via platform_data. Nicolas Ferre: I am in favor for a mainline inclusion through linux-mtd tree. Hans-Christian Egtvedt: I'm fine by sending the changes for AVR32 through linux-mtd Signed-off-by:

According to our new prefix rules, we should rename NAND_CREATE_EMPTY_BBT with a NAND_BBT prefix, i.e., NAND_BBT_CREATE_EMPTY. Signed-off-by:

Brian Norris authored
The NAND_CREATE_EMPTY_BBT flag was added by commit: 453281a9 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.

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. Signed-off-by: -

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. Signed-off-by:

Brian Norris authored
This patch handles the problems we've been having with using conflicting flags from nand.h and bbm.h in the same nand_chip.options field. We should try to separate these two spaces a little more clearly, and so I have added a bbt_options field to nand_chip. Important notes about nand_chip fields: * bbt_options field should contain ONLY flags from bbm.h. They should be able to pass safely to a nand_bbt_descr data structure. - BBT option flags start with the "NAND_BBT_" prefix. * options field should contian ONLY flags from nand.h. Ideally, they should not be involved in any BBT related options. - NAND chip option flags start with the "NAND_" prefix. * Every flag should have a nice comment explaining what the flag is. While this is not yet the case on all existing flags, please be sure to write one for new flags. Even better, you can help document the code better yourself! Please try to follow these conventions to make everyone's lives easier. Among the flags that are being moved to the new bbt_options field throughout various drivers, etc. are: * NAND_BBT_SCANLASTPAGE * NAND_BBT_SCAN2NDPAGE and there will be more to come. Signed-off-by: -

This patch reverts most of: commit 58373ff0 mtd: nand: more BB Detection refactoring and dynamic scan options According to the discussion at: http://lists.infradead.org/pipermail/linux-mtd/2011-May/035696.html the NAND_BBT_SCANBYTE1AND6 flag, although technically valid, can break some existing ECC layouts that use the 6th byte in the OOB for ECC data. Furthermore, we apparently do not need to scan both bytes 1 and 6 in the OOB region of the devices under consideration; instead, we only need to scan one or the other. Thus, the NAND_BBT_SCANBYTE1AND6 flag is at best unnecessary and at worst a regression. Signed-off-by:

Commit db64fe02 ("mm: rewrite vmap layer") introduced code that does address calculations under the assumption that VMAP_BLOCK_SIZE is a power of two. However, this might not be true if CONFIG_NR_CPUS is not set to a power of two. Wrong vmap_block index/offset values could lead to memory corruption. However, this has never been observed in practice (or never been diagnosed correctly); what caught this was the BUG_ON in vb_alloc() that checks for inconsistent vmap_block indices. To fix this, ensure that VMAP_BLOCK_SIZE always is a power of two. BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=31572 Reported-by:

Sometimes host->clock could be zero which is a legal situation. This patch checks host->clock before usage as a denominator when timeout is calculated.
