The 'param' parameter has never been used since its introduction, so
simply remove it.

Guillaume LECERF 4a58948669 mtd: add support for switching old SST chips into QRY mode
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.

Massimo Cirillo 23af51ecfb mtd: cfi_cmdset_0002: add 0xFF intolerance for M29W128G
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.

David Woodhouse c314dfdc35 [MTD] [NOR] Rename and export new cfi_qry_*() functions
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.

Alexey Korolev 2e489e077a [MTD] [NOR] Add qry_mode_on()/qry_omde_off() to deal with odd chips
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 )

Adrian Bunk 59018b6d2a MTD/JFFS2: remove CVS keywords
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This patch therefore removes all usages of the no longer updated CVS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.

Untested, but shouldn't break anything... Makes MTD_XIP arch

Tim Schmielau cd354f1ae7 [PATCH] remove many unneeded #includes of sched.h
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).

Todd Poynor d88f977b85 [MTD] CHIPS: Recognize Spansion CFI 1.4 chips
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.

Linus Torvalds 1da177e4c3 Linux-2.6.12-rc2
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!
