The A80 is a big.LITTLE SoC with 1 cluster of 4 Cortex-A7s and 1 cluster of 4 Cortex-A15s. This patch adds support to bring up the second cluster and thus all cores using custom platform SMP code. Core/cluster power down has not been implemented, thus CPU hotplugging is not supported. Parts of the trampoline and re-entry code for the boot cpu was adapted from the MCPM framework.
