From: EvanLloyd <evan.ll...@arm.com>
This v4 series of patches corrects a problem detected on the ARM Juno
platform that is actually generic (at least to ARM GIC platforms).
The HardwareInterrupt protocol had no means of handling characteristics
like Edge/Level triggered and polarity.
A new HardwareInterrupt2 protocol (provided by Ard) is added, and code
changed to utilise the new capabilities.
The code is available for examination on Github at:
https://github.com/EvanLloyd/tianocore/tree/376_irqtype_v4
v4 responds to further comments from maintainers, being mainly
cosmetic changes.
Note: Significant defects exist in the (original) Watchdog handling,
and a new patch will follow.
Ard Biesheuvel (3):
EmbeddedPkg: Introduce HardwareInterrupt2 protocol
ArmPkg/ArmGicDxe: Expose HardwareInterrupt2 protocol
ArmPkg/GenericWatchdogDxe: Set Watchdog interrupt type
Evan Lloyd (1):
ArmPkg: Tidy GIC code before changes.
