Change Details

This is enough to allow this ASUS router to reboot successfully. I tried the watchdog path and although it fires, it isn't rebooting! It's just hanging, likely somewhere in TZ. This is the MVP required to initialise and consume random data from the QCA PRNG hardware found on the IPQ401x.

* MVP for doing an SoC reset * A simple qcom_rnd random entropy driver * A simple SCM implementation for doing SMC calls into the QCOM TZ firmware, enough for this chipset to set the cold boot address for MP * Bring the MPs up and out of reset to start SMP * The reset controller side of the gcc (clock + reset) hardware block
