[PATCH v2 0/5] ARM: Berlin: SMP support

This series adds the SMP support for Marvell Berlin BG2 and BG2Q.

This implementation takes advantage of the reset exception register and
the software reset address register to make the CPUs execute the Berlin
secondary startup when being reset. This has the advantage of not using
the pen lock mechanism.

Patch 3 depends on Alex Elder effort to properly document CPU enable
methods: https://patchwork.kernel.org/patch/4138211/

Changes since v1:
	- added a proper enable-method documentation
	- s/reseted/reset/ and s/register/vector/
	- removed unneeded 'select SMP'
