                      depending on which information the caller\r
                      is requesting. PAL interprets these bits\r
                      as input parameters on two occasions. The\r
                      first time is when SAL passes control back\r
                      to PAL after the firmware recovery check.\r
                      The second time is when a call to\r
                      PAL_TEST_PROC is made. When PAL interprets\r
                      these bits it will only interpret\r
                      implemented test_control bits and will\r
                      ignore the values located in the\r
                      unimplemented test_control bits. PAL\r
                      interprets the implemented bits such that\r
                      if a bit contains a zero, this indicates\r
                      to run the test. If a bit contains a one,\r
                      this indicates to PAL to skip the test. If\r
                      the cs bit indicates that control is not\r
                       available, the test_control bits will be\r
                      ignored or generate an illegal argument in\r
                      procedure calls if the caller sets these\r
                      bits.\r
\r
  @param ControlSupport   This bit defines if an implementation\r
                          supports control of the PAL self-tests\r
                          via the self-test control word. If\r
                          this bit is 0, the implementation does\r
                          not support control of the processor\r
                          self-tests via the self-test control\r
                          word. If this bit is 1, the\r
                          implementation does support control of\r
                          the processor self-tests via the\r
                          self-test control word. If control is\r
                          not supported, GR37 will be ignored at\r
