* [PATCH] propagate mode through open_bdev_excl/close_bdev_exclAl Viro2008-10-21

* Revert "[MTD] m25p80.c code cleanup"David Woodhouse2008-10-20
| | | | | | | | | | | | | This reverts commit 75d0ee2202b5740e94e913d8a52f91c6557c4c81. Although it seems ObviouslyCorrect™, the spi_write() call uses DMA, while spi_write_then_read() does not. Since our buffer is on the stack, we must use the latter even though we don't actually want to read anything back.

* [MTD] make dataflash write-verify be optionalDavid Brownell2008-08-07
| | | | | | | | | | | | | | | | | This adds a WRITE_VERIFY Kconfig option to the DataFlash driver, closely mirroring the similar NAND and ONENAND options, giving an option to disable some code that's currently always enabled. Removing this step probably saves a millisecond or so per page when writing data, which will add up quickly since these pages are small (the largest is 1 KiB). It doesn't seem to add a lot in terms of reliability, and wouldn't detect errors which crop up when transferring data to the on-chip SRAM buffer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The wrong version of the "teach dataflash about binary density" patch just got merged (v2 not v3) ... this restores the missing updates: * Fix the cmdlinepart *regression* that caused testing failures (!!) by restoring the original part labels in relevant cases. * Don't reference things that don't exist (!) - An opcode that doesn't even exist for DataFlash - The part is "at45db642" not "at45db641" - ID zero in this JEDEC table * Make the JEDEC probe routine report and handle errors better: - If the SPI calls fail, return the error codes. - Don't depend on ordering of table entries. - Unrecognized ids are different from parts that have no ID. We won't actually know how to handle them correctly; display the ID and ignore the chip. * Move the original block comment about the "legacy" chip ID scheme back next to the code to which it applies ... not next to the new JEDEC query code, which uses an entirely different strategy. * Don't print a guessed erasesize; /proc/mtd has the real value.

All of these can use the same core operations and are newer chips that support the JEDEC "read id" instruction: - Atmel AT25 and AT26 (seven chips) - Spansion S25SL (five chips) - SST 25VF (four chips) - ST M25, M45 (five more chips) - Winbond W25X series (seven chips) That JEDEC instruction is now used, either to support a sanity check on the platform data holding board configuration data, or to determine chip type when it's not included in platform data. In fact, boards that don't need a standard partition table may not need that platform data any more. For chips that support 4KiB erase units, use that smaller block size instead of the larger size (usually 64KiB); it's less wasteful. (Tested on W25X80.)
