* mtd: MXC NAND driver fixes (v5)Vladimir Barinov2009-05-29
| | | | | | | | | | | | | | | | | | | | The following patch fixes: - re-initialization of host->col_addr which is used as byte index between the successive READID flash commands. - compile error when CONFIG_PM is enabled - pass on the error code from clk_get() - return -ENOMEM in case of failed ioremap() - pass on the return value of platform_driver_probe() directly - remove excessive printk - let command line partition table parsing with mxc_nand name. The cmd_line parsing is done via <mtd-id> name that differs from mxc_nand by default and looks like "NAND 256MiB 1,8V 8-bit" Signed-off-by: Vladimir Barinov <vbarinov@embeddedalley.com> Signed-off-by: Lothar Wassmann <LW@KARO-electronics.de> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | Extend erase timeout in M25P80 SPI Flash driver. The M25P80 drivers fails erasing sectors on a M25P128 because the ready wait timeout is too short.

| * mtd: Bug in m25p80.c during whole-chip eraseSteven A. Falco2009-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a logic error in "whole chip erase" for the m25p80 family. If the whole device is successfully erased, erase_chip() will return 0, and the code will fall through to the "else" clause, and do sector-by-sector erase in addition to the whole-chip erase. This patch corrects that. Also, the MAX_READY_WAIT_COUNT is insufficient for an m25p16 connected to a 400 MHz powerpc. Increasing it allows me to successfully program the device on my board.

| * mtd: expose subpage size via sysfsArtem Bityutskiy2009-04-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MTD has got sysfs support in 2.6.30-rc1. But subpage size is not exposed there - do this. UBI utilities badly need this parameter. At the moment there is no way to get subpage size - ioctls do not return it. And we just got sysfs support, so we can easilly extend it with this additional parameter. This can be merged late in the development cycle because: 1. sysfs support has been just added - there are no users for it so far, even. 2. UBI utilities really need this parameter, and it is better not to delay this. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

| * | [MTD] [NAND] FSL-UPM: Add wait flags to support board/chip specific delaysWolfgang Grandegger2009-04-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NAND flash on the TQM8548_BE modules requires a short delay after running the UPM pattern. The TQM8548_BE requires a further short delay after writing out a buffer. Normally the R/B pin should be checked, but it's not connected on the TQM8548_BE. The existing driver uses similar fixed delay points. To manage these extra delays in a more general way, I introduced the "fsl,ump-wait-flags" property allowing the board- specific driver to specify various types of extra delay.

MTD drivers should set the dev.parent field to point to the physical device, before setting up partitions or otherwise declaring MTDs. - Those device nodes always map to /sys/class/mtdX device nodes, which no longer depend on MTD_CHARDEV. - Those mtdX sysfs nodes have a "starter set" of attributes; it's not yet sufficient to replace /proc/mtd. - Enabling MTD_CHARDEV provides /sys/class/mtdXro/ nodes and the /sys/class/mtd*/dev attributes (for udev, mdev, etc). - Include a MODULE_ALIAS_CHARDEV_MAJOR macro. It'll work with udev creating the /dev/mtd* nodes, not just a static rootfs. So the sysfs structure is pretty much what you'd expect, except that readonly chardev nodes are a bit quirky.

But now this is also possible: console=ttyMTD,log which selects the MTD named "log" for mtdoops.

| * | [MTD] TXx9 SoC NAND Flash Memory Controller driverAtsushi Nemoto2009-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for the integrated NAND flash controller of the TXx9 family. Once upon a time there were tx4925ndfmc and tx4938ndfmc driver. They were removed due to bitrot in 2005. This new driver is completely rewritten based on a driver in CELF patch archive.

| * | [MTD] partitioning utility predicatesDavid Brownell2009-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move mtd_has_partitions() and mtd_has_cmdlinepart() inlines from a DaVinci-specific driver to the <linux/mtd/partitions.h> header. Use those to eliminate #ifdefs in two drivers which had their own definitions of mtd_has_partitions(). Quite a lot of other MTD drivers could benefit from using use one or both of these to remove #ifdeffery. Maybe some Janitors would like to help.

| * | [MTD] we don't need no misc devicesDavid Brownell2009-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove <linux/miscdevice.h> from various drivers which don't actually use any of its contents. There are still a number of these left in arch-specific bits of the tree. (Found by diffing results of "grep -rl" for linux/miscdevice.h and for misc_register, examining the differences, and verifying removals with a build test.)
