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

 - fixup casting style according to lkml feedback
 - rewrite driver so that it can handle arbitrary of

Sharp Zaurus SL-C3200 with CONFIG_MTD=m and CONFIG_MTD_SHARP_SL=y (as it
is bool) lost support for the ROM flash. With CONFIG_MTD=y it has no
problems.

It is caused by losing of compiled code of
drivers/mtd/maps/sharpsl-flash.o.
It was linked to drivers/mtd/maps/built-in.o and drivers/mtd/built-in.o,
but lost and not linked to drivers/built-in.o (because CONFIG_MTD!=y).

Patch below fixes this problem by creating sharpsl-flash.ko (and the
code works correctly as a module).

The Vermilion Range Expansion Bus supports four chip selects, each of which
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).

This patch contains a handful of small fixes to allow the Ebony's
flash to be exposed as MTD devices via the physmap_of driver.
Specifically it:
	- Makes a small addition to the device tree and zImage wrapper
to record the correct address for the flash in the device tree based
on the board switches as reported via an FPGA register.
	- Prohibits building the old hard-coded "Ebony" flash map on
arch/powerpc kernels, in favour of using physmap_of's device tree
based approach.
	- Enables MTD and physmap_of in the Ebony defconfig.
