[PATCH v2 1/5] ARM: sun9i: Support SMP on A80 with Multi-Cluster Power Management (MCPM)

2017-12-29 Thread Mylène Josserand
From: Chen-Yu Tsai 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 the common MCPM code. Core/cluster power down has not been implemented, thus CPU
