Library for Arm's GIC
This library provides APIs for Arm's GIC.
Initialization
Primary CPU from secure world

// Primary CPU initialization
// Enable the secure GIC distributor interface
// Enable SPIs, PPIs & SGIs
gicv2.distif_init(&props);
// Per CPU initialization
// Enable the Group 0 SGIs and PPIs

// Enable secure interrupts and use FIQs
// Disable legacy bypass

nightly and aarch64's target are required.
$ cargo +nightly build --target=aarch64-unknown-none-softfloat
Before building, you have to install the target as follows.
$ rustup target add --toolchain nightly aarch64-unknown-none-softfloat
