                             are used. The following functional identifiers are defined:
                             0x01XXXXXX - Architected SAL functional group.
                             0x02XXXXXX to 0x03XXXXXX - OEM SAL functional group. Each OEM is
                             allowed to use the entire range in the 0x02XXXXXX to 0x03XXXXXX range.
                             0x04XXXXXX to 0xFFFFFFFF - Reserved.
  @param  Arg1               The first parameter of the architected/OEM specific SAL functions.
  @param  Arg2               The second parameter of the architected/OEM specific SAL functions.
  @param  Arg3               The third parameter passed to the ESAL function based.
  @param  Arg4               The fourth parameter passed to the ESAL function based.
  @param  Arg5               The fifth parameter passed to the ESAL function based.
  @param  Arg6               The sixth parameter passed to the ESAL function.
  @param  Arg7               The seventh parameter passed to the ESAL function based.

  @return r8                 Return status: positive number indicates successful,
                             negative number indicates failure.
          r9                 Other return parameter in r9.
