This patch adds sh7366 cpu supports. Just the most basic things like interrupt
controller, clocks and serial port are included at this point.

Using "attr" twice is not OK, because it effectively prohibits such
container_of() on variables not named "attr".

This patch removes interrupt priority tables from the intc code.
Optimal priority assignment varies with embedded application anyway,
so keeping the interrupt priority tables together with cpu-specific
code doesn't make sense.
The function intc_set_priority() should be used instead to set the
desired interrupt priority level.

This adds in the L1I/L1D/L2 cache shape support to their respective
entries in the ELF auxvt, based on the Alpha implementation. We use
this on the userspace libc side for calculating a tightly packed
SHMLBA amongst other things.

Presently most of the 29-bit physical parts do P1/P2 segmentation
with a 1:1 cached/uncached mapping, jumping between the two to
control the caching behaviour. This provides the basic infrastructure
to maintain this behaviour on 32-bit physical parts that don't map
P1/P2 at all, using a shiny new linker section and corresponding
fixmap entry.

This implements kernel-level atomic rollback built on top of gUSA,
as an alternative non-IRQ based atomicity method. This is generally
a faster method for platforms that are lacking the LL/SC pairs that
SH-4A and later use, and is only supportable on legacy cores.

This adds support for the SH7263 (SH-2A) CPU.
This particular CPU is a superset of SH7203, adding some additional
peripheral blocks and hooking up additional (reserved on SH7203)
vectors in the INTC block.
No visibly nasty surprises, yet..

There is no need for kobject_unregister() anymore, thanks to Kay's
kobject cleanup changes, so replace all instances of it with
kobject_put().

Stop using kobject_register, as this way we can control the sending of

The ST40 stuff in-tree hasn't built for some time, and hasn't been
updated for over 3 years. ST maintains their own out-of-tree changes
and rebases occasionally, and that's ultimately where all of the ST40
users go anyways.
In order for the ST40 code to be brought up to date most of the stuff
removed in this changeset would have to be rewritten anyways, so there's
very little benefit in keeping the remnants around either.

This was all reworked some time ago, the old debug_enter was ripped
out with everything going through a debug trap jump table instead.
Kill off the debug_enter target and reference kgdb_handle_exception
directly.

Currently clock propagation only works for one level, but we have some
clocks which need to propagate multiple levels, so make this recursive.

Not all of the SH-X2 URAM blocks are mapped in the same place,
SH7785 happens to map it on the opposite end of the address space
from SH7722, correct the addresses.

This moves off of smp_processor_id() and only sets the probe
information for the boot CPU directly. This will be copied out
for the secondaries, so there's no reason to do this each time.
This also allows for some header tidying.

There was some debug code left in here that caused the pin changes
to never be hit. Kill that off, and all is well.

The probing logic works for both URAM and L2, with no way to
distinguish between the two. Disable the probing for now and
let the CPU subtypes that have this in a real L2 configuration
explicitly say so.

This adds basic support for SH-X3 SMP (4 CPUs).
More IPI and cache debugging is necessary, mostly interfacing the
d-cache coherency and the I-cache broadcast invalidates. Only for
testing at present!

There was a very preliminary bunch of SMP code scattered around for the
SH7604 microcontrollers from way back when, and it has mostly suffered
bitrot since then. With the tree already having been slowly getting
prepped for SMP, this plugs in most of the remaining platform-independent
bits.

This implements initial support for the SMP INTC (particularly
INTC2) controllers.
These are largely implemented as conventional blocks, with
register sets grouped together at fixed strides relative to
the CPU id.
