Support for NVIDIA's Tegra T210 SoCs
T210 is the latest chip in the Tegra family of SoCs from NVIDIA. It is an
ARM v8 dual-cluster (A57/A53) SoC, with any one of the clusters being active
at a given point in time.
This patch adds support to boot the Trusted Firmware on T210 SoCs. The patch
also adds support to boot secondary CPUs, enter/exit core power states for
all CPUs in the slow/fast clusters. The support to switch between clusters
is still not available in this patch and would be available later.
