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.
Cummulative patch of changes that are not vendor-specific:
- ARMv6 and ARMv7 architecture support
- ARM SMP support
- VFP/Neon support
- ARM Generic Interrupt Controller driver
- Simplification of startup code for all platforms
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.
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.

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.
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.

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.
