| 008c751 | Maxim Levitsky | 15 October 2010, 15:20:43 UTC | mtd: allow to unload the mtdtrans module if its block devices aren't open Now it once again possible to remove mtdtrans module. You still need to ensure that block devices of that module aren't mounted. This is due to the fact that as long as a block device is open, it still exists, therefore if we were to allow module removal, this block device might became used again. This time in addition to code review, I also made the code pass some torture tests like module reload in a loop + read in a loop + card insert/removal all at same time. The blktrans_open/blktrans_release don't take the mtd table lock because: While device is added (that includes execution of add_mtd_blktrans_dev) the lock is already taken Now suppose the device will never be removed. In this case even if we have changes in mtd table, the entry that we need will stay exactly the same. (Note that we don't look at table at all, just following private pointer of block device). Now suppose that someone tries to remove the mtd device. This will be propagated to trans driver which _ought_ to call del_mtd_blktrans_dev which will take the per device lock, release the mtd device and set trans->mtd = NULL. >From this point on, following opens won't even be able to know anything about that mtd device (which at that point is likely not to exist) Also the same care is taken not to trip over NULL mtd pointer in blktrans_dev_release.

| 7cba7b1 | Sebastian Andrzej Siewior | 30 September 2010, 19:28:01 UTC | mtd: nand: add support for BBT without OOB The first (sixt) byte in the OOB area contains vendor's bad block information. During identification of the NAND chip this information is collected by scanning the complete chip. The option NAND_USE_FLASH_BBT is used to store this information in a sector so we don't have to scan the complete flash. Unfortunately the code stores a marker in order to recognize the BBT in the OOB area. This will fail if the OOB area is completely used for ECC. This patch introduces the option NAND_USE_FLASH_BBT_NO_OOB which has to be used with NAND_USE_FLASH_BBT. It will then store BBT on flash without touching the OOB area. The BBT format on flash remains same except the first page starts with the recognition pattern followed by the version byte. This change was tested in nandsim and it looks good so far :) Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com> | 24 October 2010, 23:53:48 UTC |

This patch prevents caching in case of uncorrectable ECC errors. The reason is that we want to allow the user to re-read the NAND page several times. In case of unstable bits re-trying may help. Moreover, current behavior is wrong because the first read returns -EBADMSG (correctly) but the second read succeeds and incorrectly returns 0 (because we read from the cache).

| 13ed7ae | Brian Norris | 20 August 2010, 19:36:12 UTC | mtd: nand: support new Toshiba SLC Toshiba does not use ONFI for their NAND flash. So we have to continue to add new IDs used by Toshiba devices as well as heuristic detection for scanning the 2nd page for a BBM. This is a relatively harmless start at supporting many of them. These chips mostly follow the same ID fields of previous generations, but there is a need for a tweak. These chips introduce a strange 576 byte OOB (that's 36 bytes per 512 bytes of page). In the preliminary data, Toshiba has not defined exactly how their ID strings should decode. In the future, a new tweak must be added.

| 0ceacf3 | Brian Norris | 20 September 2010, 06:57:12 UTC | mtd: edit comments on deprecation of ioctl ECCGETLAYOUT There were some improvements and additions necessary in the comments explaining of the expansion of nand_ecclayout, the introduction of nand_ecclayout_user, and the deprecation of the ioctl ECCGETLAYOUT. Also, I found a better placement for the macro MTD_MAX_ECCPOS_ENTRIES; next to the definition of MTD_MAX_OOBFREE_ENTRIES in mtd-abi.h. The macro is really only important for the ioctl code (found in drivers/mtd/mtdchar.c) but since there are small edits being made to the user-space header, I figured this is a better location.

| cc26c3c | Brian Norris | 25 August 2010, 01:12:00 UTC | mtd: nand: expand nand_ecc_layout, deprecate ioctl ECCGETLAYOUT struct nand_ecclayout is too small for many new chips; OOB regions can be as large as 448 bytes and may increase more in the future. Thus, copying that struct to user-space with the ECCGETLAYOUT ioctl is not a good idea; the ioctl would have to be updated every time there's a change to the current largest size. Instead, the old nand_ecclayout is renamed to nand_ecclayout_user and a new struct nand_ecclayout is created that can accomodate larger sizes and expand without affecting the user-space. struct nand_ecclayout can still be used in board drivers without modification -- at least for now. A new function is provided to convert from the new to the old in order to allow the deprecated ioctl to continue to work with truncated data. Perhaps the ioctl, the conversion process, and the struct nand_ecclayout_user can be removed altogether in the future. Note: There are comments in nand/davinci_nand.c::nand_davinci_probe() regarding this issue; this driver (and maybe others) can be updated to account for extra space. All kernel drivers can use the expanded nand_ecclayout as a drop-in replacement and ignore its benefits.
