2010-10-24mtd: pxa3xx_nand: introduce default timing to reduce read id timesLei Wen
We certainly don't need to send read id command times by times, since we already know what the id is after the first read id... So create a default timing which could ensure it would successfully read id out all supported chip. Then follow the build-in table to reconfigure the timing.

2010-10-24mtd: pxa3xx_nand: condense the flash definitionLei Wen
Adding a new flash definition would need less code. Keep the platform passing flash definition method. If one flash is both defined in platform data and builtin table, driver would select the one from platform data first. By this way, platform could select the timing most suit for itself, not need to follow the common settings.

2010-10-24mtd: nand: support new Toshiba SLCBrian Norris
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. Data is taken from, among others, Toshiba TC58TxG4S2FBAxx Signed-off-by: Brian Norris <norris@broadcom.com> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

2010-10-24mtd: edit comments on deprecation of ioctl ECCGETLAYOUTBrian Norris
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.

2010-10-24mtd: nand: expand nand_ecc_layout, deprecate ioctl ECCGETLAYOUTBrian Norris
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.

2010-10-24mtd: nand: spansion S30MLxxxP supportBrian Norris
Some Spansion chips have a method for determining eraseblock size that is incompatible with similar ID chips of other sizes. This implements some heuristic detection of these differences. This patch checks for a 5-byte ID with trailing zeros as well as a 512-byte page size to ensure that chips are not misdetected as the S30MLxxxP ORNAND series.

2010-10-24Revalidate caches on lockRicardo Labiaga
Instead of blindly zapping the caches, attempt to revalidate them if the server has indicated that it uses high resolution timestamps. NFSv4 should be able to always revalidate the cache since the protocol requires the update of the change attribute on modification of the data. In reality, there are servers (the Linux NFS server for example) that do not obey this requirement and use ctime as the basis for change attribute. Long term, the server needs to be fixed. At this time, and to be on the safe side, continue zapping caches if the server indicates that it does not have a high resolution timestamp.
