2005-07-16[MTD] NAND: Fix broken bad block scan for 16 bit devicesThomas Gleixner
The previous change to read a single byte from oob breaks the bad block scan on 16 bit devices, when the byte is on an odd address. Read the complete oob for now. Remove the unused arguments from check_short_pattern() Move the wait for ready function so it is only executed when consecutive reads happen. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-06-29[MTD] NAND: Reorganize chip lockingThomas Gleixner
The code was wrong in several aspects. The locking order was inconsistent, the device aquire code did not reset a variable after a wakeup and the wakeup handling was not working for applications where multiple chips are sharing a single hardware controller. When a hardware controller is available the locking is now reduced to the hardware controller lock and the waitqueue is moved to the hardware controller structure in order to avoid a wake_up_all(). The problem was pointed out by Ben Dooks, who also found the missing variable reset as main cause for his deadlock problem. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-05-23[MTD] NAND: Fix the broken dynamic array allocationsJarkko Lavinen
Reverting the change from 1.136 to 1.137 (back to static allocation of ecc arrays) due to stack corruption and ecc errors. Signed-off-by: Jarkko Lavinen <jarkko.lavinen@nokia.com> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-05-23[MTD] NAND: Fix missing NULL pointer checkDan Brown
Version 1.137 broke nand_read_ecc clients who pass NULL oobsel. Fixed. Signed-off-by: Dan Brown <dan_brown@ieee.org> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-05-23[MTD] NAND: Use cond_resched instead of msleepThomas Gleixner
Replace msleep by cond_resched. On machines with HZ=100 (e.g. ARM) msleep slows down the operation by factor 10 Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
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>

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>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
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!
