Raspberry Pi 4 interrupt handling: gic400.library 1.1
The gic400.library makes the Arm GIC-400 interrupt controller of a Raspberry Pi 4 available under AmigaOS. It is designed to bundle interrupt logic that can then be used by various device drivers, such as genet.device. Changes in version 1.1:
- unroute all SPIs from CPU 0 before enabling the controller
- Updated register clobber lists in inline assembly
- Changed return value when an out-of-range IRQ is acknowledged
