368dd5acd1 MN10300: And Panasonic AM34 subarch and implement SMP
Implement the Panasonic MN10300 AM34 CPU subarch and implement SMP support for
MN10300.  Also implement support for the MN2WS0060 processor and the ASB2364
evaluation board which are AM34 based.

278d91c460 MN10300: Make the FPU operate in non-lazy mode under SMP
Make the FPU operate in non-lazy mode under SMP so that when the process that
is currently using the FPU migrates to a different CPU, we don't have to ping
its previous CPU to flush the FPU context.

0bd3eb6ca7 MN10300: SMP: Differentiate local cache flushing
Differentiate local cache flushing from global cache flushing so that they can
be done differently on SMP systems.

Rename the cache functions from:

	mn10300_[id]cache_*()

to:

	mn10300_[id]_localcache_*()

and on a UP system, assign the global labels to the local labels.

a116956423 MN10300: Move DMA engine control reg defs to MN103E010 processor directory
Move the DMA engine control register definitions to the MN103E010 processor
directory so that the MN2WS0050 processor can have its own.

2f2a2132ff Separate out the proc- and unit-specific header directories from the general
MN10300 arch headers and place them instead in the same directories as contain
the .c files for the processor and unit implementations.

This permits the symlinks include/asm/proc and include/asm/unit to be
dispensed with.  This does, however, require that #include <asm/proc/xxx.h> be
converted to #include <proc/xxx.h> and similarly for asm/unit -> unit.

b920de1b77 mn10300: add the MN10300/AM33 architecture to the kernel
Add architecture support for the MN10300/AM33 CPUs produced by MEI to the
kernel.

This patch also adds board support for the ASB2303 with the ASB2308 daughter
board, and the ASB2305.  The only processor supported is the MN103E010, which
is an AM33v2 core plus on-chip devices.
