Implement mips_cdmm_phys_base() for Malta, returning the physical base
address 0x1fc10000 which is "typically unused".
This allows the Common Device Memory Map (CDMM) region to be mapped, and
devices in that region (such as the Fast Debug Channel (FDC) hardware
for communication over EJTAG) to be discovered.

Add MIPS Common Device Memory Map (CDMM) support in the form of a bus in
the standard Linux device model. Each device attached via CDMM is
discoverable via an 8-bit type identifier and may contain a number of
blocks of memory mapped registers in the CDMM region. IRQs are expected
to be handled separately.
Due to the per-cpu (per-VPE for MT cores) nature of the CDMM devices,
all the driver callbacks take place from workqueues which are run on the
right CPU for the device in question, so that the driver doesn't need to
be as concerned about which CPU it is running on. Callbacks also exist
for when CPUs are taken offline, so that any per-CPU resources used by
the driver can be disabled so they don't get forcefully migrated. CDMM
devices are created as children of the CPU device they are attached to.
Any existing CDMM configuration by the bootloader will be inherited,
however platforms wishing to enable CDMM should implement the weak
mips_cdmm_phys_base() function (see asm/cdmm.h) so that the bus driver
knows where it should put the CDMM region in the physical address space
if the bootloader hasn't already enabled it.
A mips_cdmm_early_probe() function is also provided to allow early boot
or particularly low level code to set up the CDMM region and probe for a
specific device type, for example early console or KGDB IO drivers for
the EJTAG Fast Debug Channel (FDC) CDMM device.

Add architectural definitions and probing for the MIPS Common Device
Memory Map (CDMM) region. When supported and enabled at a particular
physical address, this region allows some number of per-CPU devices to
be discovered and controlled via MMIO.
A bit exists in Config3 to determine whether the feature is present, and
a CDMMBase CP0 register allows the region to be enabled at a particular
physical address.

Before release 2 of the architecture there weren't separate interrupt
pending bits for the local CPU interrupts (timer & perf counter
overflow), so when they were connected to the same interrupt line the
timer handler had to call the performance counter handler before knowing
whether a timer interrupt was actually pending.
Now another CPU local interrupt, for the Fast Debug Channel (FDC), can
also be routed to an arbitrary interrupt line. It isn't scalable to keep
adding cross-calls between handlers for these cases of shared interrupt
lines, especially since the FDC could in theory share its interrupt line
with the performance counter, timer, or both.
Fortunately since release 2 of the architecture separate interrupt
pending bits do exist in the Cause register. This allows local
interrupts which share an interrupt line to have separate handlers using
IRQF_SHARED. Unfortunately they can't easily have their own irqchip as
there is no generic way to individually mask them.
Enable this sharing to happen by removing the special case for when the
perf count shares an IRQ with the timer. cp0_perfcount_irq and
cp0_compare_irq can then be set to the same value with shared interrupt
handlers registered for both of them.
Pre-R2 code should be unaffected. cp0_perfcount_irq will always be -1
and the timer handler will contnue to call into the perf counter
handler.

When requesting the performance counter overflow interrupt, pass flags
which are compatible with the cevt-r4k driver, in particular
IRQF_SHARED so that the two handlers can share the same IRQ. This is
possible since release 2 of the architecture where there are separate
pending interrupt bits for the timer interrupt and the performance
counter interrupt.
This will be necessary since the FDC interrupt can also be arbitrarily
routed to a CPU interrupt, possibly sharing with the timer, the
performance counters, or both, and it isn't scalable to have all the
handlers able to call other handlers that may be on the same IRQ line.

Make the cevt-r4k interrupt handler shared so that other interrupt
handlers (specifically the performance counter overflow handler and fast

This simply imvolves returning IRQ_NONE when no timer interrupt has been

setting up the IRQ handler so that other handlers (with compatible
flags) can be registered.

moved handle_perf_irq() out of cevt-r4k.c into a header so it could be

Slightly less long ago, commit b633648c5a ("MIPS: MT: Remove SMTC

leaving cevt-r4k.c once again the sole user of handle_perf_irq(),
therefore move it back into cevt-r4k.c from the header.
