graph data in multiple banks (or bank sets), so that the least
full bank can be selected to minimize the effects of DDR3 bank
conflicts (ie: tRC=row cycle time).

driver to be aware of the o63-P2 address replication changes.
This involves changes to the MLOAD/GWALK DFA instruction format
(see: IWORD2.SREPL), as well as changes to node arc and metadata
definitions which now support an additional REPL field.

to the existing NCB address decoding scheme, the

the additional upper memory address bits to allow access

offset is directly referenced using the NCB address bits during

NOTE: The DFA_DIFCTL[MSEGBASE] is shared amongst all references.

their must be a SW mutual exclusive lock during each DFA Memory

When BLEN=0(BL2), all QW reads/writes from CP2 are
decomposed into 2 separate BL2(LW) requests to the
Low-Latency memory.
When BLEN=1(BL4), a LW request (from CP2 or NCB) is
treated as 1 BL4(QW) request to the low latency memory.
NOTE: QW refers to a 64-bit LLM Load/Store (intiated
by a processor core). LW refers to a 36-bit load/store.
NOTE: This should only be written to a different value
during power-on SW initialization before the DFA LLM
(low latency memory) is used.
NOTE: MTYPE=0(RLDRAM-II) MUST USE BLEN=0(2-burst)
NOTE: MTYPE=1(FCRAM)/BLEN=0(BL2) requires a
multi-bunk(clam) board design.
NOTE: If MTYPE=1(FCRAM)/FCRAM2P=0(II)/BLEN=1(BL4),
SW SHOULD use CP2 QW read/write requests (for
optimal low-latency bus performance).
[LW length read/write requests(in BL4 mode) use 50%
of the available bus bandwidth]
NOTE: MTYPE=1(FCRAM)/FCRAM2P=0(II)/BLEN=0(BL2) can only
be used with FCRAM-II devices which support BL2 mode
(see: Toshiba FCRAM-II, where DQ tristate after 2 data
transfers).
NOTE: MTYPE=1(FCRAM)/FCRAM2P=1(II+) does not support LW
write requests (FCRAM-II+ device specification has removed
the variable write mask function from the devices).
As such, if this mode is used, SW must be careful to
issue only PP-CP2 QW write requests. */

* DFA_MEMHIDAT = DFA NCB-Direct CSR access to DFM Memory Space (High QW)
*
* Description:
* DFA supports NCB-Direct CSR acccesses to DFM Memory space for debug purposes. Unfortunately, NCB-Direct accesses
* are limited to QW-size(64bits), whereas the minimum access granularity for DFM Memory space is OW(128bits). To
* support writes to DFM Memory space, the Hi-QW of data is sourced from the DFA_MEMHIDAT register. Recall, the
* OW(128b) in DDR3 memory space is fixed format:
* OWDATA[127:118]: OWECC[9:0] 10bits of in-band OWECC SEC/DED codeword
* This can be precomputed/written by SW OR
* if DFM_FNTCTL[ECC_WENA]=1, DFM hardware will auto-compute the 10b OWECC and place in the
* OWDATA[127:118] before being written to memory.
* OWDATA[117:0]: Memory Data (contains fixed MNODE/MONODE arc formats for use by DTEs(thread engines).
* Or, a user may choose to treat DFM Memory Space as 'scratch pad' in which case the
* OWDATA[117:0] may contain user-specified information accessible via NCB-Direct CSR mode
* accesses to DFA Memory Space.
* NOTE: To write to the DFA_MEMHIDAT register, a device would issue an IOBST directed at the DFA with addr[34:32]=3'b111.
* To read the DFA_MEMHIDAT register, a device would issue an IOBLD64 directed at the DFA with addr[34:32]=3'b111.
*
* NOTE: If DFA_CONFIG[DTECLKDIS]=1 (DFA-DTE clocks disabled), reads/writes to the DFA_MEMHIDAT register do not take effect.
* NOTE: If FUSE[TBD]="DFA DTE disable" is blown, reads/writes to the DFA_MEMHIDAT register do not take effect.
