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>

2005-05-24[MTD] Make map_word_ff ware of the flash buswidthThomas Gleixner
map_word_ff() was setting the mapword to ~0UL regardless of the buswidth of the mapped flash chip. The read_map functions are buswidth aware and therefor the map_word_equal function failed. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2005-05-23[MTD] Add reboot notifier to Intel NOR flash driverNicolas 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.

2005-01-05[MTD] Bug in 2.6.10 mtd driver for physmem mapped flash chipsDavid Woodhouse
The patch below fixes a small but fatal bug in the code that handles non-buswidth-aligned writes. The problem is that the code used the same index in both map_word and buf, therefore putting the wrong words in the map_word that partially contains old data and partially contains new data. The result: corrupt data is being written. Signed-off-by: Koen Martens <kmartens@sonologic.nl> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2004-11-16MTD: Provide XIP support for Intel flash chips.David Woodhouse
This allows for MTD support to be used on flash memory which is also used for XIP purposes, either XIP kernel or XIP userspace. The whole idea is to relocate functions actually modifying the flash state away from array mode to ram and run them with interrupt disabled. When the flash needs some time to complete a certain operation, we poll the processor for pending (but still masked) interrupts, and when they occur we suspend the flash operation in order to unmask interrupts and let the system run again.

2004-10-21MTD: NAND flash driver updates.Thomas Gleixner

2004-10-21MTD: NOR flash chip driver updatesDavid Woodhouse
Mostly from Eric Biederman for supporting BIOS flash. - Move support firmware hub style lock and unlock into fhw_lock.h (from cfi_cmdset_0002) - Move cfi_varsize_frob into cfi_util from cfi_cmdset_0001.c and cfi_cmdset_0002.c - reduce gen_probe probe failuers to a debug level message - Modify cfi_fixup to take a struct mtd_info instead of a struct map_info So that the fixup routines can modify the mtd functions. - Modify cfi_cmdset_0001() to allocate and initialize the mtd structure before calling cfi_fixup. - Modify cfi_cmdset_0002() to allocate and initialize the mtd structure before calling cfi_fixup. - Refactor the hard coded fixups in cfi_cmdset_0001 and cfi_cmdset_0002 so the improved cfi_fixup infrastructure. - Rewrote amd76xrom and ichxrom. They now report their starting physical address in their name. They now both handle multiple bankwidth configurations They both can create multipe mtd devices. They both now assume the rom windows are properly opened by the BIOS or whatever runs previous to them. Their code is now synchromized so it is almost identical, and could be a starting point for a x86_rom_probe. Signed-Off-By: David Woodhouse <dwmw2@infradead.org>

2004-08-10Fix use-after-free bug in MTD partitioning code.David Woodhouse
Define callback wrapper function mtd_erase_callback() to handle partition offsets during the callback, rather than attempting to fix them up in the freed erase_info structure after the callback has already happened.

2004-07-12[PATCH] sparse: switching afs to kvecAlexander Viro
- afs and rxrpc switched to kvec; definition of kvec moved to uio.h (duh). - afs/mntpt.c got missing cast added. at that point afs is sparse-clean and rxrpc has only one remaining warning (setsockopt from local variable, protected by set_fs()).

mtd, jffs and jffs2 switched from iovec to kvec
2004-06-23[PATCH] sparse: trivial drivers/char/* annotation and format fixesAlexander Viro
- trivial annotation in several places in drivers/mtd - a bunch of debugging printks switched from %x to %llx (they get 64bit values) - in doc200[01].c fixed type of (unused) last argument in their doc_read_ecc().
2003-06-23Replace mtd_blktrans ->ioctl() method with ->getgeo() and ->flush()David Woodhouse
... and also fix the embarrassing bug where NFTL and INFTL will barf and exit if the add_mtd_blktrans_dev() function _exists_, rather than actually calling it and barfing if it returns non-zero :)
