2005-05-23[MTD] ixp2000: Remove port setting codeLennert Buytenhek
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.

2005-05-23[MTD] NAND: Use cond_resched instead of msleepThomas Gleixner

2005-05-23[MTD] NAND: Check command timeoutThomas Gleixner
Check timeout while we wait for the command to finish. No worry about a false result. This prevents deadlocking when detecting an unknown number of chips and is useful for removable media too. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-05-23[MTD] Fixup probing logic for single 16bit devicesBen Dooks
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>
2005-05-23[MTD] NAND: Read only OOB bytes during bad block scanArtem B. Bityuckiy
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. Correctly free the this->bbt array in case of failure. Tested with Large page NAND. Fix debugging message. Signed-off-by: Artem B.

2005-05-23[MTD] NAND: Allow operation without bad block tableArtem B. Bityuckiy

2005-05-23[MTD] User interface to Protection RegistersNicolas Pitre
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.

2005-05-23[MTD] Support for protection register support on Intel FLASH chipsNicolas Pitre
This enables support for reading, writing and locking so called "Protection Registers" present on some flash chips. A subset of them are pre-programmed at the factory with a unique set of values.

2005-05-23[MTD] Fix MTD device probingRussell King
Try larger numbers of chips before smaller numbers of chips across the bus width. This means we'll avoid misdetecting a 2 x16 array as 1 x32 if the high 16-bits happen to read as zeros in the QRY area.
