1161298251 Create a common set_stackptrs in sys/arm/machdep.c.
On single core devices set_stackptrs is only ever called with cpu = 0 in
initarm and will be identical to the existing function. On SMP this needs
to be implemented for sys/arm/mp_machdep.c, but the implementations are
identical for each SoC.

when building each kernel.

86bce74937 Move unmask IRQ function call up to nexus device level.
FDT-enabled targets were broken after r238043 that relies
on device up the hierarchy to properly setup interrupt.
nexus device for ARM platforms did job only partially:
setting handler but not unmasking interrupt. Unmasking
was performed by platform code.

3590dad094 More Linux boot support. Create arm_dump_avail_init() to initialize
this array either from Linux boot data, when enabled, or in the
typical way that most ports do it.  arm_pyhs_avail_init is coming
soon since it must be a separate function.

d39655d7a4 Modify all the arm platform files to call parse_boot_param passing in
the boot parameters from initarm first thing.  parse_boot_param parses
the boot arguments and converts them to the /boot/loader metadata the
rest of the kernel uses.  parse_boot_param is a weak alias to
fake_preload_metadata, which all the platforms use now, but may become
more extensive in the future.

Since it is a weak symbol, specific boards may define their own
parse_boot_param to interface to custom boot loaders.

4623180919 Minor rearrangement of the locore <-> initarm interface. Pass in a
structure with the first 4 registers to allow a wider range of boot
loaders to work.  Future commits will make use of this to centralize
support for the different loaders.

c08ce26e98 Move the load address of the kernel to the start of KVA as the
s3c24x0 copy of initarm expects the kernel to be loaded there.

c305730dc0 Remove bogus usage of INTR_FAST. "Fast" interrupts are now indicated by
registering a filter handler rather than a threaded handler.  Also remove
a bogus use of INTR_MPSAFE for a filter.

6eae6892da Rework how device memory is allocated on the s3c24x0 CPU's.
The device virtual addresses are now able to be allocated at runtime rather
than from the static pmap_devmap at boot. The only exception is memory
required before we have had a chance to dynamically allocate it.

While here reduce the space between the statically allocated devices by
reducing the distance between the virtual addresses.

30e980f2d1 Add support for the Samsung S3C2xx0 family of ARM SoCs written by
Andrew Turner.  The kernel supports the LN2410SBC evaluation board,
and likely others.  These parts (or similar ones) are in some open
hardware designs for phones.
