Usage

Example from https://github.com/andre-richter/rust-raspi3-tutorial

```rust extern crate cortex_a;

[no_mangle]

pub unsafe extern "C" fn bootcores() -> ! { use cortex_a::{asm, regs::*};

const CORE_MASK: u64 = 0x3;
const STACK_START: u64 = 0x80_000;

match MPIDR_EL1.get() & CORE_MASK {
    0 => {
        SP.set(STACK_START);
        reset()
    }
    _ => loop {
        // if not core0, infinitely wait for events
        asm::wfe();
    },
}

} ```
