SMCCC and PSCI functions for bare-metal Rust on aarch64
This crate provides support for the Arm SMC Calling Convention version 1.4, including standard Arm Architecture Calls constants, and version 1.1 of the Arm Power State Coordination Interface (PSCI). It includes constants, functions to make the calls (on aarch32 and aarch64 targets), and error types.
Note that the PSCI and SMCCC arch calls may be made via either HVC or SMC. You can choose which one
to use by passing either Hvc or Smc as a type parameter to the relevant function.
