* mtd: add support for switching old SST chips into QRY modeGuillaume LECERF2009-11-301-0/+7
| | | | | | | | | | SST 39VF160x/39VF320x and some old SST chips need a special command sequence to enter CFI QueRY mode [1]. This patch adds the relevant sequence to cfi_qry_mode_on(). Tested with 39VF3201. Signed-off-by: Guillaume LECERF <glecerf@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
* mtd: cfi_cmdset_0002: add 0xFF intolerance for M29W128GMassimo Cirillo2009-09-191-0/+4
| | | | | | | | | | | | | | The M29W128G Numonyx flash devices are intolerant to any 0xFF command: in the Cfi_util.c the function cfi_qry_mode_off() (that resets the device after the autoselect mode) must have a 0xF0 command after the 0xFF command. This fix solves also the cause of the fixup_M29W128G_write_buffer() fix, that can be removed now. The following patch applies to 2.6.30 kernel.

* [MTD] [NOR] Rename and export new cfi_qry_*() functionsDavid Woodhouse2008-08-071-11/+15
| | | | | | | | | | They need to be exported, so let's give them less generic-sounding names while we're at it. Original export patch, along with the suggestion about the nomenclature, from Stephen Rothwell. Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
* [MTD] [NOR] Add qry_mode_on()/qry_omde_off() to deal with odd chipsAlexey Korolev2008-08-061-4/+58
| | | | | | | | | | | | | | | | | | | | | | | | | There are some CFI chips which require non standard procedures to get into QRY mode. The possible way to support them would be trying different modes till QRY will be read. This patch introduce two new functions qry_mode_on qry_mode_off. qry_mode_on tries different commands in order switch chip into QRY mode. So if we have one more "odd" chip - we just could add several lines to qry_mode_on. Also using these functions remove unnecessary code duplicaton in porbe procedure. Currently there are two "odd" cases 1. Some old intel chips which require 0xFF before 0x98 2. ST M29DW chip which requires 0x98 to be sent at 0x555 (according to CFI should be 0x55) This patch is partialy based on the patch from Uwe (see "[PATCH 2/4] [RFC][MTD] cfi_probe: remove Intel chip workaround" thread ) Signed-off-by: Alexey Korolev <akorolev@infradead.org> Signed-off-by: Alexander Belyakov <abelyako@gmail.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
* MTD/JFFS2: remove CVS keywordsAdrian Bunk2008-06-041-3/+0
| | | | | | | | | | | | Once upon a time, the MTD repository was using CVS. This patch therefore removes all usages of the no longer updated CVS keywords from the MTD code. This also includes code that printed them to the user. Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: David Woodhouse <dwmw2@infradead.org>

* [PATCH] remove many unneeded #includes of sched.hTim Schmielau2007-02-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

* [MTD] CHIPS: Recognize Spansion CFI 1.4 chipsTodd Poynor2005-08-041-10/+1
| | | | | | | | | | | | | | | | Modify Amd/Fujitsu CFI NOR flash primary vendor extension table revision check to recognize version 1.4. Verified the existing driver can handle version 1.4 chips without additional info from 1.4 extended table. Move the primary vendor extension table revision check from common file to the 3 CFI chip driver files, since the data structures and revisions handled by those data structures are specific to the chip driver. Modify the error message printed when the revision is unknown to be a KERN_ERR instead of WARNING since this will cause mtd to ignore the chip.

* Linux-2.6.12-rc2Linus Torvalds2005-04-161-0/+196
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
