de591dacf3 MTD: Fix bug in fixup_convert_atmel_pri
The memset() in fixup_convert_atmel_pri is supposed to zero out
everything except the first 5 bytes in *extp, but it ends up zeroing
out something way outside the struct instead. Fix this potentially
dangerous code by casting the pointer to char * before doing
arithmetic.

fb8d81e477 [PATCH] MTD NAND: Fix ams-delta after core conversion
The recent hwctrl core conversion for MTD NAND devices broke the Amstrad
Delta driver.  This fixes it up and uses the existing control line defines
rather than unclear magic numbers.

0165508c80 MTD: Add lock/unlock operations for Atmel AT49BV6416
The AT49BV6416 is locked by default, so we really need to provide
at least the unlock() operation for write and erase to work. This
patch implements both ->lock() and ->unlock() and provides a fixup
to install them when an AT49BV6416 chip is detected.

These functions are probably valid on more Atmel chips, but I believe
it's mostly obsolete ones. The AT49BV6416 is in fact obsolete, but
it's used on all current AT32STK1000 development boards.

5b0c5c2c0d MTD: Convert Atmel PRI information to AMD format
Atmel flash chips don't have PRI information in the same format as
AMD flash chips. This patch installs a fixup for all Atmel chips that
converts the relevant PRI fields into AMD format.

Only the fields that are actually used by the command set is actually
converted. The rest are initialized to zero (which should be safe)

46a1652c28 [MTD] Fixes of performance and stability issues in CFI driver.
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

c4e7fb3137 block2mtd.c: Make kernel boot command line arguments work (try 4)
Trying to pass kernel command line arguments to block2mtd at boot-time does
not work currently. block2mtd_setup() is called so early that kmalloc()
fails nevermind being able to do open_bdev_excl() (which requires rootfs to
be mounted. This patch only saves the option string at the early boot stage,
and parses them later when block2mtd_init() is called. If open_bdev_excl()
fails, open_by_devnum(name_to_dev_t()) is tried instead, which makes it
possible to initialize the driver before rootfs has been mounted. Also gets
rid of the superfluous parse_name() that only checks if name is longer than
80 chars and copies it to a string that is not kfreed.

With this patch, I can boot statically compiled block2mtd, and mount jffs2
as rootfs (without modules or initrd), with lilo config like this:

   root=/dev/mtdblock0
   append="rootfstype=jffs2 block2mtd.block2mtd=/dev/hdc2,65536"

(Note that rootfstype=jffs2 is required, since the kernel only tries
filesystems without "nodev" attribute by default, and jffs is "nodev").

Compared to first version of this patch, this one does not copy the
parameters to the global buffer if init has already been called, and the
global array is marked as __initdata.

Compared to the second version of this patch, module build is fixed.

Compared to the third version of this patch, statically compiled block2mtd
driver with no boot-time parameter no longer gives spurious error 'cannot
open device ""'

73c619ea0e [MTD] Disconnect struct mtd_info from ABI
mtdchar.c direcly copied part of struct mtd_info to userspace, thereby
implicitly making it part of the ABI.  With this patch, struct
mtd_info is independent of the ABI and can have its fields removed,
reordered, etc.

92cbfdcc36 [MTD] replace MTD_RAM with MTD_GENERIC_TYPE
Ram devices get the extra capability of MTD_NO_ERASE - not requiring
an explicit erase before writing to it.  Currently only mtdblock uses
this capability.  Rest of the patch is a simple text replacement.

e369d62e92 [MTD] replace MTD_ROM with MTD_GENERIC_TYPE
No mtd user should ever check for the device type.  Instead, device features
should be checked by the flags - if at all.
As a first step towards type removal, change MTD_ROM into MTD_GENERIC_TYPE.
