/** CM_ARM_GICC_INFO parser function.

|
|
This parser expects FdtBranch to be the "\cpus" node node.
|
|
At most one CmObj is created.
|
|
The following structure is populated:
|
|
typedef struct CmArmGicCInfo {
|
|
UINT32 CPUInterfaceNumber; // {Populated}
|
|
UINT32 AcpiProcessorUid; // {Populated}
|
|
UINT32 Flags; // {Populated}
|
|
UINT32 ParkingProtocolVersion; // {default = 0}
|
|
UINT32 PerformanceInterruptGsiv; // {Populated}
|
|
UINT64 ParkedAddress; // {default = 0}
|
|
UINT64 PhysicalBaseAddress; // {Populated}
|
|
UINT64 GICV; // {Populated}
|
|
UINT64 GICH; // {Populated}
|
|
UINT32 VGICMaintenanceInterrupt; // {Populated}
|

UINT64 GICRBaseAddress; // {default = 0}

UINT64 MPIDR; // {Populated}

} CM_ARM_GICC_INFO;
|
|
|
|
A parser parses a Device Tree to populate a specific CmObj type. None,
|
|
one or many CmObj can be created by the parser.
|
|
The created CmObj are then handed to the parser's caller through the
|
|
HW_INFO_ADD_OBJECT interface.
|
|
This can also be a dispatcher. I.e. a function that not parsing a
|
|
Device Tree but calling other parsers.
|
|
|
|
@param [in] FdtParserHandle A handle to the parser instance.
|
|
@param [in] FdtBranch When searching for DT node name, restrict
|
|
the search to this Device Tree branch.
|
|
|
|
@retval EFI_SUCCESS The function completed successfully.
|
|
@retval EFI_ABORTED An error occurred.
|
|
@retval EFI_INVALID_PARAMETER Invalid parameter.
|
|
@retval EFI_NOT_FOUND Not found.
|
|
@retval EFI_UNSUPPORTED Unsupported.
