The existing HardwareInterrupt protocol lacked a means to configure the level/edge properties of an interrupt. The new HardwareInterrupt2 protocol introduced this capability. This patch updates the GIC drivers to provide the new interfaces. The changes comprise: Update to use HardwareInterrupt2 protocol Additions to register info in ArmGicLib.h Added new functionality (GetTriggerType and SetTriggerType) The requirement for this change derives from a problem detected on ARM Juno boards, but the change is of generic (ARM) relevance. This commit is in response to review on the mailing list and, as suggested there, rolls Girish's updates onto Ard's original example.
