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.

We support SRAM and NOR flash devices only by registering appropriate

This driver seems to be obsolete and broken for a long time.
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

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.

 - drop superfluous casts
 - drop SSYNC() when reading from the flash and rewrite
   bfin_copy_from() to be like bfin_copy_to() so that
   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

has 64MiB of address space.  The 2nd BAR of the Expansion Bus PCI Device
is a 256MiB memory region containing the address spaces for all four of
the chip selects, with start addresses hardcoded on 64MiB boundaries.

This map driver only supports NOR flash on chip select 0.  The buswidth
(either 8 bits or 16 bits) is determined by reading the Expansion Bus Timing
and Control Register for Chip Select 0 (EXP_TIMING_CS0).
