DRIVER: ARM Generic Interrupt Controller v2 - GICv2

[TunaCici]

I need to implement a somewhat "ok" driver for ARM's GICv2. Almost any kind of I/O I'll do in the future will be done thru this interrupt controller.

As of now (Feb 25, 2024) I don't know "much" about GIC. It seems PRETTYYYY big & important. So, I'll need to read tons of documentations & guide and "real-world" resources.

I'll people not implement it 100% myself, as it's not really the smartest thing to do. There are pretty decent implementations of GICv2 out there; they'll be a good point to start.

In fact; ARM providing a public "reference" implementation of these kinds of stuff: ARM-software/arm-trusted-firmware. If I also want to "get good" at systems security, this might be a good resource to help me in that regard.

This'll be a long journey
