This service is identical + in functionality to AsmPalCall() in the functions of the Base Library specific to Intel Itanium architecture. + The only difference is that the PAL Entry Point is not passed in. Implementations + of this library class must manage PAL Entry Point on their own. For example, a PEI + implementation can use a PPI to lookup the PAL Entry Point, and a DXE implementation + can contain a constructor to look up the PAL Entry Point from a HOB.

If a PAL procedure is specified as optional, a unique return + code of 0xFFFFFFFFFFFFFFFF is returned in the Status field of the PAL_CALL_RETURN structure. + This indicates that the procedure is not present in this PAL implementation.

Any address + passed to PAL as buffers for return parameters must be 8-byte aligned. Unaligned addresses + may cause undefined results.
