OMAP-L137/AM17x has limited number of dedicated EMIFA
address pins, enough to interface directly to an SDRAM.
If a device such as an asynchronous flash needs to be
attached to the EMIFA, then either GPIO pins or a chip
select may be used to control the flash device's upper
address lines.

This patch adds support for the NOR flash on the OMAP-L137/
AM17x user interface daughter board using the latch-addr-flash
MTD mapping driver which allows flashes to be partially
physically addressed. The upper address lines are set by
a board specific code which is a separate patch.

(Commit 7cb777a3 (mtd: add ARM pismo support)
intended to add this, but seems only to have patched the Makefile without
touching Kconfig or providing any code...)

The following patch adds support for PISMO modules found on ARM Ltd
development platforms.  These are MTD modules, and can have a
selection of SRAM, flash or DOC devices as described by an on-board
I2C EEPROM.

We support SRAM and NOR flash devices only by registering appropriate
conventional MTD platform devices as children of the 'pismo' device.

It depends on CONFIG_IPAQ_HANDHELD that simply doesn't exists
anywhere in kernel. Also, it seems that none of machines it
claims to support have any use of it:
 SA11xx-based iPAQs (h3100/h3600) use sa1100-flash
 iPAQ h5000 uses physmap-flash

There isn't any benefit to building the uClinux MTD map as a module as the
rootfs it requires in order to actually be usable is appended to the
kernel image, not the module.  No known system builds it this way either,
so change the option to "bool".

The RAMROOT function was a successful but non-portable attempt to append
the root filesystem to the end of the kernel image.  The preferred and
portable solution is to use an initramfs instead.

The only user of this function was the msp71xx configuration
in the MIPS architecture; as the use of the RAMROOT has been removed
from that configuration, there are no more users, so this code
can be removed.

This patch adds support for the Sega Dreamcast visual memory unit as a
flash mapping. It requires changes in the maple bus driver (posted
separately) to support block reads and writes.

The VMU is a 'smart' flash device, with a built-in 8-bit controller -
for instance there is an erase before a write but it is hidden from the
user. But the device's overall behaviour means it works well with the
mtd layer and it is appropriate to add it as an mtd mapping.

The current method for always showing physmap compat address, size, and
width is a bit confusing.  If length is set to 0, then the address and
width are still shown but silently unused.  The physmap code itself
already has logic which sets compat based on length, so just pull that out
and into the Kconfig to make everything clear.

 - drop superfluous casts
 - drop SSYNC() when reading from the flash and rewrite

   we dont have to handle all the aligned/unaligned cases

[try #3] rename bf5xx-flash to bfin-async-flash
 - move all kconfig board settings into board resources
 - fixup casting style according to lkml feedback
 - rewrite driver so that it can handle arbitrary of
