[PATCH 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 being reseted. This has the advantage of
not using the pen lock mechanism.
