      [MTD] Fix fwh_lock locking · e6be133b
      由 Shashi Rao 提交于 
      This is on a custom board with a mapping driver access to an ST
M50LPW080 chip. This chip is probed successfully with
do_map_probe("jedec_probe",...). If I use the mtdchar interface to
perform unlock->erase->program->lock on any of the 16 eraseblocks in the
chip, the chip is left in FL_STATUS mode while the data structures
believe that the chip is in FL_READY mode. Hence, any subsequent reads
to any flash byte results in 0x80 being read.

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      由 Tim Schmielau 提交于 
      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] Fixes of performance and stability issues in CFI driver. · 46a1652c
      由 Alexey Korolev 提交于 
      Fix of performance and stability issues on Intel NOR chips. It fixes:

1. Very low write performance on Sibley (perf tests demonstrated write
   performance less than 100Kb/sec when it should be over 400Kb/sec).

2. Low erase performance. (perf tests on Sibleuy demonstrated erase
   performance 246Kb/sec when it should be over 300Kb/sec).

3. Error on JFFS2 tests with CPU loading application when MTD returns
   "block erase error: (status timeout)" To fix the issue it does the
   following:
     1. Removes the timeout tuning from inval_cache_and_wait_for_operation.
     2. Waiting conditions in inval_cache_and_wait_for_operation now is
         based on timer resolution
        If timeout is lower than timer resolution then we do in cycle
	  "Checking the status"
	  udelay(1);
	  cond_resched();
        If timeout is greater than timer resolution (probably erase
        operation) We do the following
	  sleep for half of operation timeout and do in cycle the following
	    "Checking the status"
	    sleep for timer resolution

      [MTD] Introduce MTD_BIT_WRITEABLE · 5fa43394
      由 Joern Engel 提交于 
      o Add a flag MTD_BIT_WRITEABLE for devices that allow single bits to be
  cleared.
o Replace MTD_PROGRAM_REGIONS with a cleared MTD_BIT_WRITEABLE flag for
  STMicro and Intel Sibley flashes with internal ECC.  Those flashes
  disallow clearing of single bits, unlike regular NOR flashes, so the
  new flag models their behaviour better.
o Remove MTD_ECC.  After the STMicro/Sibley merge, this flag is only set
  and never checked.

      [MTD] Merge STMicro NOR_ECC code with Intel Sibley code · c8b229de
      由 Joern Engel 提交于 
      In 2002, STMicro started producing NOR flashes with internal ECC protection
for small blocks (8 or 16 bytes).  Support for those flashes was added by me.
In 2005, Intel Sibley flashes copied this strategy and Nico added support for
those.  Merge the code for both.

      [MTD] Introduce writesize · 28318776
      由 Joern Engel 提交于 
      At least two flashes exists that have the concept of a minimum write unit,
similar to NAND pages, but no other NAND characteristics.  Therefore, rename
the minimum write unit to "writesize" for all flashes, including NAND.
