[PATCH v3 0/5] ARM: SMP: support Broadcom mobile SoCs

[Alex Elder]

This series adds SMP support for two Broadcom mobile SoC families.
It uses CPU_METHOD_OF_DECLARE() so that SMP operations are assigned
using device tree rather than adding it to a machine definition in a
board file.

The enable method starts a secondary core by writing to a register
monitored by CPUs spinning in a ROM-based holding pen loop.  The
address of this register is recorded as a property in the "cpus"
node of the device tree.

Note:
This series is based on v3.15-rc4, plus one more recently-posted patch:

History
v3: - Dropped definition and use of CPU_METHOD_OF_DECLARE_SETUP()
    - Added documentation for "enable-method"
    - Rebased onto v3.15-rc4
v2: - Fixed a Makefile error (:= should have been +=)
