73566edf9b [MTD] Convert physmap to platform driver
After dwmw2 let me know it ought to be done, I rewrote the physmap map
driver to be a platform driver.  I know zilch about the driver model,
so I probably botched it in some way, but I've done some tests on an
ixp23xx board which uses physmap, and it all seems to work.

In order to not break existing physmap users, I've added some compat
code that will instantiate a platform device iff CONFIG_MTD_PHYSMAP_LEN
is defined and != 0.  Also, I've changed the default value for
CONFIG_MTD_PHYSMAP_LEN to zero, so that people who inadvertently
compile in physmap (or new, platform-style, users of physmap) don't get
burned.

This works pretty well -- the new physmap driver is a drop-in replacement
for the old one, and works on said ixp23xx board without any code changes
needed.  (This should hold as long as users don't touch 'physmap_map'
directly.)

Once all physmap users have been converted to instantiate their own
platform devices, the compat code can go.  (Or we decide that we can
change all the in-tree users at the same time, and never merge the
compat code.)

7d532dd50d ts72xx NAND driver
The TS-72xx is a series of embedded single board computers from
Technologic Systems based on the Cirrus ep93xx (arm920t based) CPU.

The TS-7200 uses NOR flash, while all the other models in the series
(TS-7250, TS-7260) use NAND flash -- included is a driver for the NAND
flash on those boards.

954c242273 mtd: improve parameter parsing for block2mtd
Expand the parameter parsing for block2mtd.  It now accepts:
Ki, Mi, Gi	- the official prefixes for binary multiples,
		  see http://physics.nist.gov/cuu/Units/binary.html,
ki		- mistake on my side and analog to "k" for decimal multiples,
KiB, MiB, GiB	- for people that prefer to add a "B" for byte,
kiB		- combination of the above.

There were complaints about not accepting "k" for 1024.  This has long
been common practice, but is known to lead to confusion.  Hence the new
SI units and hence block2mtd only accepts units that cannot be confused
with decimal units.  Diverging from common practice doesn't always please
people, even if the change is for the better.

7f7c08dfdf Simplify test for RAM devices
mtdblock is the only user of aggregate capabilities in mtd.  This is clearly
bogus and should be changed.  In particular, it tries to determine whether
the device in question is a piece of RAM.  For every single driver that fits
the current criteria, an easier test would be to check for the type being
MTD_RAM.

acc8dadc0b [PATCH] Remove blkmtd
Remove the blkmtd driver.

- An alternative exists (block2mtd) that hasn't had  bug report for > 1 year.

- Most embedded people tend to use ancient kernels with custom patches from
  mtd cvs and elsewhere, so the 1 year warning period neither helps nor hurts
  them too much.

- It's in the way of klibc.  The problems caused by pulling blkmtd support
  are fairly low, while the problems caused by delaying klibc can be fairly
  substantial.  At best, this would be a severe burden on hpa's time.

b175d03dd2 [PATCH] mtd cmdlinepart: allow zero offset value

For example, I can split 4MB device using "mtdparts=id:2M,2M", but I can

partition and allows 0 for offset value.

8d3b33f67f [PATCH] Remove MODULE_PARM
MODULE_PARM was actually breaking: recent gcc version optimize them out as
unused.  It's time to replace the last users, which are generally in the
most unloved drivers anyway.

3cb4f09fc2 [PATCH] mtd_dataflash, fix block vs page erase
Fix a bug in the block-erase optimization for Dataflash; it was using block
erase even for smaller segments that need page erase.

That wouldn't matter for JFFS2, which never erases less than one block
(sometimes several blocks), but for other callers it might.

9cff3372bf [PATCH] drivers/mtd/redboot.c: recognise a foreign byte sex partition table
The RedBoot boot loader writes flash partition tables containing native
byte sex 32 bit values.  When booting an opposite byte sex kernel (e.g.  an
LE kernel from BE RedBoot) the current MTD driver fails to handle the
partition table and therefore is unable to generate the correct partition
map for the flash.

So far as I am aware this problem is ARM specific, because only ARM
supports software change of the CPU (memory system) byte sex, however the
partition table parsing is in generic MTD code.  The patch below has been
tested on NSLU2 (an IXP4XX based system) with a patch,
10-ixp4xx-copy-from.patch (submitted to linux-arm-kernel - it's ARM
specific) required to make the maps/ixp4xx.c driver work with an LE kernel.

Builds of the patched system are in the 'unstable' release of OpenSlug and
UcSlugC available from www.nslu2-linux.org.  These builds are BE, the
archives at www.nslu2-linux.org and www.handhelds.org (see
monotone.vanille.de) can be built LE (currently DISTRO targets
nslu-ltu.conf for LE thumb uclibc (32 bit kernel) and nslu2-lau.conf,
nslu2-lag.conf for LE arm uclibc/glibc) and this patch has been tested
extensively will both BE and LE systems on the NSLU2 (including swapping
between BE and LE by reflashing from both RedBoot and Linux).

The patch recognises that the FIS directory (the partition table) is
byte-reversed by examining the partition table size, which is known to be
one erase block (this is an assumption made elsewhere in redboot.c).  If
the size matches the erase block after byte swapping the value then
byte-reversal is assumed, if not no further action is taken.  The patched
code is fail safe; should redboot.c be changed to support a partition table
with a modified size field the test will fail and the partition table will
be assumed to have the host byte sex.

If byte-reversal is detected the patch byte swaps the remainder of the 32
bit fields in the copy of the table; this copy is then used to set up the
MTD partition map.

d86d43706a [PATCH] cfi_cmdset_0001: fix range for cache invalidation
I found an issue in cfi_cmdset0001.c.  It is related to cache region
invalidation in the buffered write procedure.

The code performs cache invalidation from "cmd_addr" to "cmd_adr + len" in
do_write_buffer() while we modify region from "adr" to "adr+len".

This issue affects writes + reads of data by small chunks.

034d2f5af1 [PATCH] arm: fix dependencies for MTD_XIP
MTD_XIP depends on having working asm/mtd-xip.h; it's not just per-architecture
(arm-only, as current Kconfig would have it), but actually per-subarch as
well.  Introduced a new symbol (ARCH_MTD_XIP) set by arch Kconfig; MTD_XIP
depends on it.
