[edk2-devel] [PATCH v1 05/12] ArmPkg: Fix return type for ArmGicGetInterfaceIdentification
Posted by Sami Mujawar 1 year, 1 month 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.
