/*++
Routine Description:
Calculate CRC32 for target data
Arguments:
Data - The target data.
DataSize - The target data size.
CrcOut - The CRC32 for target data.
Returns:
EFI_SUCCESS - The CRC32 for target data is calculated successfully.
EFI_INVALID_PARAMETER - Some parameter is not valid, so the CRC32 is not
calculated.

/*++
Routine Description:
Determines the new virtual address that is to be used on subsequent memory accesses.
Arguments:
DebugDisposition - Supplies type information for the pointer being converted.
ConvertAddress - A pointer to a pointer that is to be fixed to be the value needed
for the new virtual address mappings being applied.
Returns:
EFI_SUCCESS - The pointer pointed to by Address was modified.
EFI_NOT_FOUND - The pointer pointed to by Address was not found to be part
of the current memory map. This is normally fatal.
EFI_INVALID_PARAMETER - One of the parameters has an invalid value.

IN EFI_MEMORY_DESCRIPTOR *VirtualMap
)
/*++
Routine Description:
Changes the runtime addressing mode of EFI firmware from physical to virtual.
Arguments:
MemoryMapSize - The size in bytes of VirtualMap.
DescriptorSize - The size in bytes of an entry in the VirtualMap.
DescriptorVersion - The version of the structure entries in VirtualMap.
VirtualMap - An array of memory descriptors which contain new virtual
address mapping information for all runtime ranges.
Returns:
EFI_SUCCESS - The virtual address map has been applied.
EFI_UNSUPPORTED - EFI firmware is not at runtime, or the EFI firmware is already in
virtual address mapped mode.
EFI_INVALID_PARAMETER - DescriptorSize or DescriptorVersion is invalid.
EFI_NO_MAPPING - A virtual address was not supplied for a range in the memory
map that requires a mapping.
EFI_NOT_FOUND - A virtual address was supplied for an address that is not found
in the memory map.

Routine Description:
Install Runtime AP. This code includes the EfiRuntimeLib, but it only
functions at RT in physical mode.
Arguments:
ImageHandle - Image handle of this driver.
SystemTable - Pointer to the EFI System Table.
Returns:
EFI_SUCEESS - Runtime Driver Architectural Protocol installed.
