* mtd_dataflash: unbreak erase supportPeter Korsgaard2009-05-181-1/+1
| | | | | | | | | | | Commit 5b7f3a50 (fix dataflash 64-bit divisions) unfortunately introduced a typo. Erase addr and len were swapped in the pageaddr calculation, causing the wrong sectors to get erased.

| | | | | | | | | | | | | | | | | | | | | | | | | | 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. Change the timeout from a simple loop count to a suitable number of seconds.

| * mtd: Bug in m25p80.c during whole-chip eraseSteven A. Falco2009-04-291-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Bityutskiy2009-04-191-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Grandegger2009-04-061-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | [MTD] TXx9 SoC NAND Flash Memory Controller driverAtsushi Nemoto2009-03-203-0/+435
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Brownell2009-03-203-34/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Brownell2009-03-206-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.)

| * | [MTD] [NAND] fix broken debug messagesDavid Brownell2009-03-201-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix incorrect debug messages (*write* not read); someone committed some cut'n'paste bugs.  There might be more, I only noticed these since I was looking for nand_read usage and landed in some very wrong functions. IMO all MTD debugging message framework is goofed, anyway. It uses "DEBUG" in a way that's incompatible with usage most everywhere else in the kernel, and which prevents normal pr_dbg() and dev_dbg() calls from working right. [True. It predates those by a long way, and should probably be updated to use them. dwmw2] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
