* [MTD] ixp2000: Remove port setting codeLennert Buytenhek2005-05-23
| | | | | | | | | | | | | | Setting the slowport to 8-bit mode is something that ought to be done in the IXP2000 generic code, not in the MTD map driver. See the description for ARM patch 2493/1 for an explanation. http://www.arm.linux.org.uk/developer/patches/viewpatch.php?id=2493/1 Now that 2493/1 has been accepted and will be upstream soon, this doesn't need to be done in the map driver anymore.

* [MTD] NAND: Check command timeoutThomas Gleixner2005-05-23

* [MTD] Fixup probing logic for single 16bit devicesBen Dooks2005-05-23
| | | | | | | | | | | | | | | | | | | The change to the generic probe to look for the smallest width of chip first is causing some problems on boards with a single 16bit device. The problem seems to be the jedec_match() is truncating the device-id read from the table to match against the one read from the hardware, causing a match against the partial id of some chips with 16bit IDs (such as the SST39LF160) This fixes things for my own board, but something may need to be done if the same problem is exhibited for chips with an 8bit ID Signed-off-by: Ben Dooks <ben@simtec.co.uk> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
* [MTD] NAND: Read only OOB bytes during bad block scanArtem B. Bityuckiy2005-05-23
| | | | | | | | | | | | When scanning NAND for bad blocks, don't read the whole page, read only needed OOB bytes instead. Also check the return code of the nand_read_raw() function.

* [MTD] User interface to Protection RegistersNicolas Pitre2005-05-23
| | | | | | | | | | | This is implemented using a ioctl to switch the MTD char device into one of the different OTP "modes", at which point read/write/seek can operate on the selected OTP area. Also some extra ioctls to query for size and lock protection segments or groups. Some example user space utilities are provided.
