* | [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. Correctly free the this->bbt array in case of failure. Tested with Large page NAND. Fix debugging message. Signed-off-by: Artem B.

* | [MTD] NAND: Allow operation without bad block tableArtem B. Bityuckiy2005-05-23
| | | | | | | | | | | | | | | | Small bugfix. Sometimes it may be handy not to have bbt. So, this->bbt might be NULL. Signed-off-by: Artem B. Bityuckiy <dedekind@infradead.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

* | [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.

* | [MTD] Support for protection register support on Intel FLASH chipsNicolas Pitre2005-05-23
| | | | | | | | | | | | | | | | | | | | 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. The rest is user-programmable.

* | [MTD] Fix MTD device probingRussell King2005-05-23
| | | | | | | | | | | | | | | | | | | | | | 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.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
