  ARM: picoxcell: implement watchdog restart

Allow the platform to be restarted by triggering the watchdog to expire
with the shortest possible expiry.  This should reset the CPU core and
all on-chip peripherals.

v2:	- use writel_relaxed().

Add maintainer entry for the picoxcell machine support and associated
drivers.

v2:	- add 2-level pattern for drivers

Now that we have lost our machine specific ioremap() we just have one
mapping that covers all peripherals.  Move this to common.c to simplify
things a little.

All irq_desc's are now dynamically allocated so we don't need to
statically reserve them.

v2:	- select SPARSE_IRQ and set .nr_irqs to NR_IRQS_LEGACY to skip
	ISA and IRQ 0.

The MPP12 is listed in the 6281 HW manual as output only but the iconnect
board from iomega is using it as GPIO (there's a button connected on it). So,
I'm adding a definition for the MPP12 as GPIO. As I've no informations about
this and which kirkwood are "affected", I'm adding a new #define instead of
modifying the current one for MPP12.

Now that there is a common way to reset the machine, let's use it
instead of reinventing the wheel in the kexec backend.
Signed-off-by: Will Deacon <will.deacon@arm.com>

Sending IPI_CPU_STOP to a CPU causes it to execute a busy cpu_relax
loop forever. This makes it impossible to kexec successfully on an SMP
system since the secondary CPUs do not reset.

This patch adds a callback to platform_cpu_kill, defined when
CONFIG_HOTPLUG_CPU=y, from the ipi_cpu_stop handling code. This function
currently just returns 1 on all platforms that define it but allows them
to do something more sophisticated in the future.
Signed-off-by: Will Deacon <will.deacon@arm.com>

Tools such as kexec and CPU hotplug require a way to reset the processor
and branch to some code in physical space. This requires various bits of
jiggery pokery with the caches and MMU which, when it goes wrong, tends
to lock up the system.

This patch fleshes out the soft_restart implementation so that it
branches to the reset code using the identity mapping. This requires us
to change to a temporary stack, held within the kernel image as a static
array, to avoid conflicting with the new view of memory.
Signed-off-by: Will Deacon <will.deacon@arm.com>

When disabling the MMU, it is necessary to take out a 1:1 identity map
of the reset code so that it can safely be executed with and without
the MMU active. To avoid the situation where the physical address of the
reset code aliases with the virtual address of the active stack (which
cannot be included in the 1:1 mapping), it is desirable to change to a
new stack at a location which is less likely to alias.

This code adds a new lib function, call_with_stack:

	void call_with_stack(void (*fn)(void *), void *arg, void *sp);

which changes the stack to point at the sp parameter, before invoking
fn(arg) with the new stack selected.
