1980 * The Central Management Sequencer (CSEQ) Scratch Memory is a 1024
1981 * byte memory. It is dword accessible and has byte parity
1982 * protection. The CSEQ accesses it in 32 byte windows, either as mode
1983 * dependent or mode independent memory. Each mode has 96 bytes,
1984 * (three 32 byte pages 0-2, not contiguous), leaving 128 bytes of
1985 * Mode Independent memory (four 32 byte pages 3-7). Note that mode

1987 * independent scratch memory, pages 0-3.
1988 * - 896 bytes of mode dependent scratch, 96 bytes per Modes 0-7, and
1989 * 128 bytes in mode 8,
1990 * - 259 bytes of mode independent scratch, common to modes 0-15.
1991 *
1992 * Sequencer scratch RAM is 1024 bytes. This scratch memory is
1993 * divided into mode dependent and mode independent scratch with this
1994 * memory further subdivided into pages of size 32 bytes. There are 5
1995 * pages (160 bytes) of mode independent scratch and 3 pages of
1996 * dependent scratch memory for modes 0-7 (768 bytes). Mode 8 pages
1997 * 0-2 dependent scratch overlap with pages 0-2 of mode independent
1998 * scratch memory.
1999 *
2000 * The host accesses this scratch in a different manner from the
2001 * central sequencer. The sequencer has to use CSEQ registers CSCRPAGE
2002 * and CMnSCRPAGE to access the scratch memory. A flat mapping of the
2003 * scratch memory is avaliable for software convenience and to prevent
2004 * corruption while the sequencer is running. This memory is mapped

1358 * 1) When a link reset has completed and we got BYTES DMAED with a

1360 * the phy is up, i.e. we update the phy_is_up in DDB 0. The
1361 * sequencer checks phy_is_up when pending SCBs are to be sent, and
1362 * when an open address frame has been received.
1363 *
1364 * 2) When we know of ports, we call this function to update the map
1365 * of phys participaing in that port, i.e. we update the
1366 * port_map_by_links in DDB 0. When a HARD_RESET primitive has been
1367 * received, the sequencer disables all phys in that port.
1368 * port_map_by_links is also used as the conn_mask byte in the
1369 * initiator/target port DDB.
