Tegra210: bpmp: power management interface
This patch adds the driver to communicate with the BPMP processor
for power management use cases. BPMP controls the entry into cluster

to calculate the target state for the cluster. In case BPMP does not
allow CCx entry, the core enters a power down state.

This patch adds the implementation of the SE atomic context save

routine is responsible to validate the context-save progress
counter, where CTX_SAVE_CNT=133(SE1)/646(SE2), and the SE error
status to ensure the context save procedure complete successfully.

spm: permit platform to override the VMA placement of the vector table

table outside of the static placement of the BL31 image itself, for

supplementary linker script, in which case it will be used as the
VMA region for the vector table. Note that the LMA does not change,
