| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes broken terminology added in the "m25p80.c erase enhance" patch, which added a chip erase command but called it "block erase".

These effectively match the word address 0x555 and 0x2aa, except the latter has its low bit set. Most chips don't care about the value of the 'A-1' pin in x8 mode, but some -- like the ST M29W320D -- do. So we need to be careful to set it where appropriate. cfi_send_gen_cmd is only ever passed addresses where the low byte is 0x00, 0x55 or 0xaa. Of those, only addresses ending 0xaa are affected by this patch, by masking in the extra low bit when the device is known to be in compatibility mode. [dwmw2: Do it only when (cmd_ofs & 0xff) == 0xaa] v4: Fix stupid typo in cfi_build_cmd_addr that failed to compile I'm writing this patch way to late at night. v3: Bring all of the work back into cfi_build_cmd_addr including calling of map_bankwidth(map) and cfi_interleave(cfi) So every caller doesn't need to. v2: Only modified the address if we our device_type is larger than our bus width.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To keep the size of changesets sane we split the switch by drivers; to keep the damn thing bisectable we do the following: 1) rename the affected methods, add ones with correct prototypes, make (few) callers handle both. That's this changeset. 2) for each driver convert to new methods. *ALL* drivers are converted in this series. 3) kill the old (renamed) methods. Note that it _is_ a flagday; all in-tree drivers are converted and by the end of this series no trace of old methods remain. The only reason why we do that this way is to keep the damn thing bisectable and allow per-driver debugging if anything goes wrong. New methods: open(bdev, mode) release(disk, mode) ioctl(bdev, mode, cmd, arg) /* Called without BKL */ compat_ioctl(bdev, mode, cmd, arg) locked_ioctl(bdev, mode, cmd, arg) /* Called with BKL, legacy */ Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

Although it seems ObviouslyCorrect™, the spi_write() call uses DMA, while spi_write_then_read() does not.

For other parts it avoids the bogus "Assuming top" message. It does not detect the following correctly:- MX28F640C3B B MX29LV002C T MX29LV002NC T MX29LV004C B MX29SL400C T/B MX29SL402C T/B If desired I could supply a more complicated patch to handle these as well.

| * | [MTD] [NAND] Bug on atmel_nand HW ECC : OOB info not correctly writtenRichard Genoud2008-10-141-52/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The functions that write the OOB info (on hardware ECC only) use the HW_SYNDROME method. This is not correct : the start position is "pos = eccsize + chunk" and should be eccsize. So, the standard (nand_write_oob_std) function should be used. This patch corrects this by using NAND_ECC_HW instead of NAND_ECC_HW_SYNDROME. This has only been tested on small pages nand flash. (if anyone can test it on large pages that would be great). kernel version : 2.6.27-rc2 (current git mtd-2.6) Signed-off-by: Richard Genoud <richard.genoud@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Removed the Kconfig associated with 'NDFC NanD Flash Controller'. We can't enable !CONFIG_PPC_MERGE so there is no way to enable this. Additionally the code needs to get updated for arch/powerpc. For the time being lets just remove the Kconfig option so we can actually remove CONFIG_PPC_MERGE.

| * | [MTD] [NAND] driver extension to support NAND on TQM85xx modulesWolfgang Grandegger2008-10-102-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch extends the FSL UPM NAND driver from Anton Vorontsov to support hardware which does not have the R/B pin of the NAND chip connected, like the TQM8548 module: - The OF_GPIO dependency has been removed from the Kconfig option because GPIO is not needed. The relevant gpio_* function are then stubbed out in <linux/gpio.h>. - It re-introduces the chip-delay property to define an appropriate maximum delay time (tR) required for read operations. The binding will be documented in a separate patch. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
| * | [MTD] [NAND] fsl_upm: update driver for the new OF bindingsAnton Vorontsov2008-10-101-24/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Get rid of fsl,wait-pattern and fsl,wait-write. I think this isn't chip-specific, and we should always do waits. I saw one board that didn't need fsl,wait-pattern, but I assume this was the exception that proves the rule; - Get rid of chip-delay. Today there are no users for this, and if anyone really need this they should push the OF bindings beforehand; - Now flash chips should be child nodes of the FSL UPM NAND controller; - Implement OF partition parsing.

| * | [MTD] [INFTL] Fix infinite loop in INFTL_foldchainDaniel Rosenthal2008-10-081-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When iterating over a chain in reverse (oldest block first), this patch correctly marks the PUtable[] entry of the second to last erase block of a chain as BLOCK_NIL, regardless of whether or not it can format the last block successfully. Before, the second to last block was only marked as pointing to BLOCK_NIL if INFTL_formatblock() succeeded on the last block of the chain, which could potentially result in an infinite loop if the block was worn out and refused to format.
