To support SMP on the MSM8x16 SoCs we need to add ARMv8/64-bit SCM interfaces to setup the boot/release addresses for the secondary CPUs. In addition we need a uniquie set of cpu ops. I'm aware the desired methods for booting secondary CPUs is either via spintable or PSCI. However, these SoCs are shipping with a firmware that does not support those methods. TODO: * clean up docs related to 'qcom,arm-cortex-acc' and L2 v3: * dropped use of pen, just release CPUs directly into secondary_start v2: * Dropped introduction and use of CPU_METHOD_OF_DECLARE * Moved qcom cpu ops from drivers/soc/qcom to arch/arm64/kernel * Renamed msm to qcom in cpu ops code, minor cleans (remove dead defines/code) - k -- Qualcomm Innovation Center, Inc.
