1614 * Adapter Status Register
1616 * Phase Staus mailbox is 32bits:
1617 * <31:16> = Phase Status
1620 * The adapter reports is present state through the phase. Only
1621 * a single phase should be ever be set. Each phase can have multiple
1622 * phase status bits to provide more detailed information about the
1623 * state of the board. Care should be taken to ensure that any phase
1624 * status bits that are set when changing the phase are also valid
1625 * for the new phase or be cleared out. Adapter software (monitor,
1626 * iflash, kernel) is responsible for properly maintining the phase
1627 * status mailbox when it is running.
1631 * Phases are bit oriented. It is NOT valid to have multiple bits set
