## Summary I have a case where I want to do a very quick warm reboot without going through a bootloader, by just entering nuttx __start again. This works fine, except that GICv3 initialization may leave interrupts active. The warm reboot case can be fixed by simply disabling all interrupts at GICv3 initialization, which is implemented in this PR: - In case of warm reboot, clear active and pending interrupts from GICv3 and also from the CPU interface. - Fix default IGROUPMODR to the reset value (0) - Move gic_wait_rwp calls to after modifying ICENABLER - Improve some comments ## Impact Impacts arm64 boot, GICv3 initialization. Ensures that there are not active or pending interrupts left after GIC init. ## Testing Tested on IMX93 platform in SMP and in single core cases. -- This is an automated message from the Apache Git Service.
