mtd: nand: Move ELM driver and rename as omap_elm
The ELM driver is only used by the OMAP NAND driver, so let's move it
to the nand/ directory. Additionally, let's rename it to a less confusing
name, so the module is built with a meaningful name, instead of the previous
'elm.ko'.

mtd: st_spi_fsm: Allocate resources and register with MTD framework
This is a new driver. It's used to communicate with a special type of
optimised Serial Flash Controller called the FSM. The FSM uses a subset
of the SPI protocol to communicate with supported NOR-Flash devices.

mtd: ST SPEAr: Add SMI driver for serial NOR flash
SPEAr platforms (spear3xx/spear6xx/spear13xx) provide SMI (Serial Memory
Interface) controller to access serial NOR flash. SMI provides a simple
interface for SPI/serial NOR flashes and has certain inbuilt commands
and features to support these flashes easily. It also makes it possible
to map an address range in order to directly access (read/write) the SNOR
over address bus. This patch intends to provide serial nor driver support
for spear platforms which are accessed through SMI.

ps3/block: Replace mtd/ps3vram by block/ps3vram
Convert the PS3 Video RAM Storage Driver from an MTD driver to a plain block
device driver.
The ps3vram driver exposes unused video RAM on the PS3 as a block device
suitable for storage or swap. Fast data transfer is achieved using a local
cache in system RAM and DMA transfers via the GPU.
The new driver is ca. 50% faster for reading, and ca. 10% for writing.

Revert "[MTD] Driver for AT26Fxxx dataflash devices"
This reverts commit 340ea370c2ce89d1c15fbf785460f2f74314ce58.
It's not needed given the other m25p80 patch (which now handles
at26 "dataflash" as well as most other standard SPI flash chips),
and requires a controller driver that won't be merged upstream
(supplanted by drivers/spi/atmel_spi.c) ... the submitter of
that at91_dataflash26.c driver concurred.

[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.

[PATCH] spi: M25 series SPI flash
This was originally a driver for the ST M25P80 SPI flash. It's been
updated slightly to handle other M25P series chips.
For many of these chips, the specific type could be probed, but for now
this just requires static setup with flash_platform_data that lists the
chip type (size, format) and any default partitioning to use.

[PATCH] spi: mtd dataflash driver
This is a conversion of the AT91rm9200 DataFlash MTD driver to use the
lightweight SPI framework, and no longer be AT91-specific. It compiles
down to less than 3KBytes on ARM.
The driver allows board-specific init code to provide platform_data with
the relevant MTD partitioning information, and hotplugs.
This version has been lightly tested. Its parent at91_dataflash driver has
been pretty well banged on, although kernel.org JFFS2 dataflash support was
acting broken the last time I tried it.

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!
