2006-06-20[MTD] NAND: Fix breakage all over the placeThomas Gleixner
Following problems are addressed: - wrong status caused early break out of nand_wait() - removed the bogus status check in nand_wait() which is a relict of the abandoned support for interrupted erase. - status check moved to the correct place in read_oob - oob support for syndrom based ecc with strange layouts - use given offset in the AUTOOOB based oob operations Partially based on a patch from Vitaly Vool <vwool@ru.mvista.com> Thanks to Savin Zlobec <savin@epico.si> for tracking down the status problem.

2006-05-29[MTD] NAND Replace oobinfo by ecclayoutThomas Gleixner
The nand_oobinfo structure is not fitting the newer error correction demands anymore. Replace it by struct nand_ecclayout and fixup the users all over the place. Keep the nand_oobinfo based ioctl for user space compability reasons. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-26[MTD] NAND modularize write functionThomas Gleixner
Modularize the write function and reorganaize the internal buffer management. Remove obsolete chip options and fixup all affected users. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-25[MTD] NAND Modularize read functionThomas Gleixner
Split the core of the read function out and implement seperate handling functions for software and hardware ECC. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] NAND remove write_byte/word function from nand_chipThomas Gleixner
The previous change of the command / hardware control allows to remove the write_byte/word functions completely, as their only user were nand_command and nand_command_lp. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-23[MTD] Refactor NAND hwcontrol to cmd_ctrlThomas Gleixner
The hwcontrol function enforced a step by step state machine for any kind of hardware chip access. Let the hardware driver know which control bits are set and inform it about a change of the control lines. Let the hardware driver write out the command and address bytes directly. This gives a peformance advantage for address bus controlled chips and simplifies the quirks in the hardware drivers. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2006-05-23[MTD] NAND modularize ECCThomas Gleixner
First step of modularizing ECC support. - Move ECC related functionality into a seperate embedded data structure - Get rid of the hardware dependend constants to simplify new ECC models Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2006-05-22[MTD] Introduce writesizeJoern Engel
At least two flashes exists that have the concept of a minimum write unit, similar to NAND pages, but no other NAND characteristics. Therefore, rename the minimum write unit to "writesize" for all flashes, including NAND. Signed-off-by: Joern Engel <joern@wh.fh-wedel.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!
