+description:
+  The SoC Control Processor (SoCCP) is small RISC-V MCU that controls USB
+  Type-C, battery charging and various other functions on Qualcomm SoCs, somewhat
+  analogous to traditional PC Embedded Controllers. This document describes
+  the Peripheral Authentication Service loads and boots firmware for SoCCP.
