[v2] ArmPkg: Arm GIC Library and Driver improvements

[edk2-devel] [PATCH v2 05/11] ArmPkg: Fix return type for ArmGicGetInterfaceIdentification
Posted by Sami Mujawar 1 year, 3 months ago
The CPU Interface Identification Register (GICC_IIDR) is a 32-bit
register. Since ArmGicGetInterfaceIdentification () returns the
value read from the GICC_IIDR register, update the return type
for this function to UINT32.
