Create general kernel debugger cache flushing for MN10300 and get rid of the
old stuff that gdbstub was using.
Signed-off-by: David Howells <dhowells@redhat.com>
Introduce a general config option for kernel debugger hooks so that both
gdbstub and kgdb can use it and add a header file for both debuggers to use.

The icache invalidate functions should disable the icache on AM33 and wait for
it to quiesce before attempting to invalidate it, and should then wait for it
to quiesce again before reenabling it, but on AM34 they should invalidate
directly. The same goes for the dcache invalidation, but this isn't used much.
Whilst we're at it, this can be wrapped in assembler macros to remove duplicate
code.
The AM33 manual states that:
An operation that invalidates the cache, switches the writing mode, or
changes the way mode must be performed after disabling the cache,
checking the busy bit, and confirming that the cache is not in
operation.
for the dcache [sec 2.8.3.2.1]. This is not stated so for the icache [sec
2.8.3.1.1] but the example code there suggests that it is.
Whilst the AM34 manual states that the cache must be disabled for both the
icache [sec 1.8.3.2.1] and the dcache [sec 1.8.3.2.1], the Panasonic hardware
engineers say the manual is wrong and that disabling the caches for
invalidation is wrong.
Furthermore, they say that disabling the caches on the AM34 whilst running an
SMP kernel can lead to incoherency between the various CPU caches and should
thus be avoided.

Restrict single-stepping through the kernel using gdbstub to non-preemptable
non-SMP configs as gdbstub has to do software single-stepping by means of
temporary breakpoints. Hardware single-stepping is unavailable as Panasonic
have not sufficiently documented the interface to it.
Software single-stepping through preemptable or SMP kernels runs into problems
as it makes it much more likely that the wrong thread will hit the temporary
breakpoints. It seems impractical to work around the problem for the most
part. It could be possible to make a UP preemptable kernel switch temporary
breakpoints in and out in switch_to().

Clear the interrupt mask registers of ASB2364 peripherals before enabling
interrupts so that any peripherals that weren't dealt with by the bootloader
after a reboot (if there was one) won't cause an interrupt storm when
interrupts are first enabled before the drivers are initialised.
Also, attempt to reset the peripherals attached to the FPGA.
