2009-03-16mtd_dataflash: fix probing of AT45DB321C chips.Will Newton
commit 229cc58ba2b5a83b0b55764c6cb98695c106238a upstream. Commit 771999b65f79264acde4b855e5d35696eca5e80c ("[MTD] DataFlash: bugfix, binary page sizes now handled") broke support for probing AT45DB321C flash chips. These chips do not support the "page size" status bit, so if we match the JEDEC id return early.

2008-07-30[MTD] DataFlash: bugfix, binary page sizes now handledakpm@linux-foundation.org
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. And add a few more comments.

2008-07-11[MTD] [NAND] remove __PPC__ hardcoded address from DiskOnChip driversMilton Miller
Such a hardcoded address can cause a checkstop or machine check if the driver is in the kernel but the address is not acknowledged. Both drivers allow an address to be specified as either a module parameter or config option. Any future powerpc board should either use one of these methods or find the address in the device tree.

2007-06-28[MTD] m25p80 handles more chips, uses JEDEC ids and small eraseblocksDavid Brownell
Update chip ID tables in m25p80 to handle more SPI flash chips, matching datasheets. 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.)

2007-05-02PCI: Cleanup the includes of <linux/pci.h>Jean Delvare
I noticed that many source files include <linux/pci.h> while they do not appear to need it. Here is an attempt to clean it all up. In order to find all possibly affected files, I searched for all files including <linux/pci.h> but without any other occurence of "pci" or "PCI". I removed the include statement from all of these, then I compiled an allmodconfig kernel on both i386 and x86_64 and fixed the false positives manually. My tests covered 66% of the affected files, so there could be false positives remaining.

2007-02-20[PATCH] [MTD] block2mtd: remove readahead codeJoern Engel
Over the years there was a slow trickle of complaints against the readahead code. Most of them concerned performance, Peter Zijlstra stumbled over it when working unrelated changes and I believe there was an actual bug report. Oh, Andrew Morton also complained about duplicating code from mm/readahead.c. It is just not worth it. On flash media like usb sticks, readahead will make things go slow - very slow. On spinning disks, readahead may be a win, but this is definitely not the place to add it. Signed-off-by: Jörn Engel <joern@lazybastard.org>
