Remove the bogus definition of the MBAR register for the ColdFire 532x
family. It doesn't have an MBAR register, its peripheral registers are
at fixed addresses and are not relative to a settable base.
All the code that relyed on this definition existing has been cleaned
up. The register address definitions now include the base as required.

The ColdFire 54xx family shares the same interrupt controller used
on the 523x, 527x and 528x ColdFire parts, but it isn't offset
relative to the IPSBAR register. The 54xx doesn't have an IPSBAR
register.
By including the base address of the peripheral registers in the register
definitions (MCFICM_INTC0 and MCFICM_INTC1 in this case) we can avoid
having to define a fake IPSBAR for the 54xx. And this makes the register
address definitions of these more consistent, the majority of the other
register address defines include the peripheral base address already.

Add an m68k/coldfire optimized memmove() function for the m68knommu arch.
This is the same function as used by m68k. Simple speed tests show this
is faster once buffers are larger than 4 bytes, and significantly faster
on much larger buffers (4 times faster above about 100 bytes).
This also goes part of the way to fixing a regression caused by commit
ea61bc461d ("m68k/m68knommu: merge MMU and
non-MMU string.h"), which breaks non-coldfire non-mmu builds (which is
the 68x328 and 68360 families). They currently have no memmove() fucntion
defined, since there was none in the m68knommu/lib functions.

Some versions of gcc replace calls to strstr() with single-character
"needle" string parameters by calls to strchr() behind our back.
If strchr() is defined as an inline function, this causes linking errors
like
ERROR: "strchr" [drivers/target/target_core_mod.ko] undefined!
As m68k is the only architecture that has an inline strchr() and this
inline version is not an optimized asm version, uninline strchr() and use
the standard out-of-line C version in lib/string.c instead.
This also decreases the defconfig/allmodconfig kernel image sizes by a few
hundred bytes.

Create separate functions to deal with instruction and data cache flushing.
This way we can optimize them for the vairous cache types and arrangements
used across the ColdFire family.
For example the unified caches in the version 3 cores means we don't
need to flush the instruction cache. For the version 2 cores that do
not do data cacheing (or where we choose instruction cache only) we
don't need to do any data flushing.

Currently the code to push cache lines is only available to version 4

path that does all the right things on all version cores.

The cache control code for the ColdFire CPU's is a big ugly mess
of "#ifdef"ery liberally coated with bit constants. Clean it up.
The cache controllers in the various ColdFire parts are actually quite
similar. Just differing in some bit flags and options supported. Using
the header defines now in place it is pretty easy to factor out the
small differences and use common setup and flush/invalidate code.
I have preserved the cache setups as they where in the old code
(except where obviously wrong - like in the case of the 5249). Following
from this it should be easy now to extend the possible setups used on
the CACHE controllers that support split cacheing or copy-back or
write through options.

The ColdFire UART base addresses varies between the different ColdFire

Fix the IRQ flag handling naming. In linux/irqflags.h under one configuration,
it maps:
local_irq_enable() -> raw_local_irq_enable()
local_irq_disable() -> raw_local_irq_disable()
local_irq_save() -> raw_local_irq_save()
...
and under the other configuration, it maps:
raw_local_irq_enable() -> local_irq_enable()
raw_local_irq_disable() -> local_irq_disable()
raw_local_irq_save() -> local_irq_save()
...
This is quite confusing. There should be one set of names expected of the
arch, and this should be wrapped to give another set of names that are expected
by users of this facility.
Change this to have the arch provide:
flags = arch_local_save_flags()
flags = arch_local_irq_save()
arch_local_irq_restore(flags)
arch_local_irq_disable()
arch_local_irq_enable()
arch_irqs_disabled_flags(flags)
arch_irqs_disabled()
arch_safe_halt()
Then linux/irqflags.h wraps these to provide:
raw_local_save_flags(flags)
raw_local_irq_save(flags)
raw_local_irq_restore(flags)
raw_local_irq_disable()
raw_local_irq_enable()
raw_irqs_disabled_flags(flags)
raw_irqs_disabled()
raw_safe_halt()
with type checking on the flags 'arguments', and then wraps those to provide:
local_save_flags(flags)
local_irq_save(flags)
local_irq_restore(flags)
local_irq_disable()
local_irq_enable()
irqs_disabled_flags(flags)
irqs_disabled()
safe_halt()
with tracing included if enabled.
The arch functions can now all be inline functions rather than some of them
having to be macros.
