ArmPkg/ArmGicDxe: annotate protocol usage in "ArmGicDxe.inf"
"ArmGicDxe.inf" currently does not document how the protocols in the
[Protocols] section are used. Such comments help us analyze behavior, so
let's add them now.
- gHardwareInterruptProtocolGuid and gHardwareInterrupt2ProtocolGuid are
always produced on the InterruptDxeInitialize() -> (GicV2DxeInitialize()
| GicV3DxeInitialize()) -> InstallAndRegisterInterruptService() call
path.
- gEfiCpuArchProtocolGuid is consumed in the CpuArchEventProtocolNotify()
protocol notify callback. (Technically this is "conditional"; however
the firmware cannot work without architectural protocols, so we can call
it unconditional.)
While at it, drop the gArmGicDxeFileGuid comment from FILE_GUID; we're
going to make that GUID uninteresting soon.
