2005-01-05MTD: Cosmetic ident catchup.David Woodhouse2-2/+2
Let the CVS idents catch up where changes have been made upstream. Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2005-01-05[MTD] Bug in 2.6.10 mtd driver for physmem mapped flash chipsDavid Woodhouse1-2/+2
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>

some trivial iomem annotations were still missing Signed-off-by: Al Viro <viro@parcelfarce.linux.theplanet.co.uk> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2004-12-13MTD XIP support: allyesconfig compile fix.Nicolas Pitre1-2/+10
People insist on turning stuff on which doesn't make sense. Make it compile in the case where the platform doesn't provide the necessary XIP primitives. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

2004-11-16MTD: NAND driver updatesDavid Woodhouse1-1/+7
- Support 2048-byte HW ECC (from Juha Yrjölä <juha.yrjola@nokia.com>) - Allow board drivers to provide pattern for bad block scanning Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: David Woodhouse <dwmw2@infradead.org>
2004-11-16MTD: Provide XIP support for Intel flash chips.David Woodhouse2-1/+102
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.

2004-11-16MTD: some cleanupsDavid Woodhouse1-2/+1

2004-10-21MTD: NAND flash driver updates.Thomas Gleixner1-3/+17
- Use new RS library for ECC - Add support for new NAND flash chips - New board support: - iPAQ H1910 - Renesas AG-AND devel board - Simtec S3C210 - Support for shared controllers on multiple chips.

2004-10-21MTD: NOR flash chip driver updatesDavid Woodhouse1-14/+26
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>

2004-10-19[PATCH] #include <asm/bitops.h> -> #include <linux/bitops.h>Adrian Bunk1-1/+1
There's no reason to directly #include <asm/bitops.h> since it's available on all architectures and also included by #include <linux/bitops.h>.

2004-08-10Fix use-after-free bug in MTD partitioning code.David Woodhouse1-1/+13
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 Viro1-5/+0
- 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 Viro1-1/+1
- 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 Woodhouse1-10/+7
... 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 :)

From: Rusty Russell <rusty@rustcorp.com.au> I don't think it's misused anywhere, but it's better to be safe. Pointed out by Joern Engel.

2002-10-14[MTD] Update 2.5 MTD code from MTD CVS and ARM treeRussell King1-0/+23
This cset updates the 2.5 MTD code from the MTD CVS. David Woodhouse is happy with me sending this. Summary of changes: - Add MTD device concatenation support module. - Bootldr MTD partition parsing is obsolete, replaced by command-line based partition information. - Add support for ARM map drivers: AUTCPU12, Ceiva, Camelot, Fortunet, edb7312, Impa7, PCI - Add support for PCMCIA memory cards - Update help texts for: Ocelot, ITE QED-4N-S01B, Flaga Please note that this does not completely synchronise the 2.5 kernel tree with MTD CVS.
2002-08-10[PATCH] clean up major_nameAlexander Viro1-0/+1
->major_name for per-disk gendisks set to full name - i.e. IDE gendisks have "hda", "hdb", etc. instead of "hd". As the result, we kill a lot of crap in check.c::disk_name(). In particular, now we can afford ->minor_shift set to 0 for ide-cd (disk_name() was the only obstacle)
