ARM: sun9i: Support SMP bring-up on A80 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. Signed-off-by: Chen-Yu Tsai <wens@csie.org>

ARM: sunxi: fix build for THUMB2_KERNEL Building an SMP kernel for the sunxi platform with THUMB2 instructions fails with this error at the moment: headsmp.S:7: Error: Thumb encoding does not support an immediate here -- `msr cpsr_fsxc,#0xd3' Since the generic secondary_startup function already does the same thing in a safe way, we can just drop the private sunxi implementation and jump straight to secondary_startup.
