                                                             1) When RANK_ENA=0, SW must properly configure the PBANK_LSB to

                                                             2) When RANK_ENA=1 (dual ranks), SW must configure PBANK_LSB to

                                                         For example, for a DFM DDR3 memory populated using Samsung's k4b1g0846c-f7
                                                         1Gb(256MB) (16M x 8 bit x 8 bank) DDR3 parts, the column address width = 10 and
                                                         the device row address width = 14b.  The single x8bit device contains 128MB, and
                                                         requires TWO such parts to populate the DFM 16b DDR3 interface. This then yields
                                                         a total rank size = 256MB = 2^28.
                                                         For a single-rank configuration (RANK_ENA=0), SW would program PBANK_LSB>=3 to

                                                         For a dual-rank configuration (RANK_ENA=1), SW would program PBANK_LSB=4 to select
                                                         rank=mem_adr[28] as the bit used to determine which 256MB rank (of 512MB total) to

                                                         DFM DDR3 data bus.
                                                         The DFM DDR3 memory controller supports either 1(or 2) rank(s) based
                                                         on how much total memory is desired for the DFA application. See

                                                         SW NOTE:
                                                             1) When RANK_ENA=0, SW must properly configure the PBANK_LSB to
                                                                reference upper unused memory address bits.
                                                             2) When RANK_ENA=1 (dual ranks), SW must configure PBANK_LSB to
                                                                reference the upper most address bit based on the total size
                                                                of the rank.
                                                         For example, for a DFM DDR3 memory populated using Samsung's k4b1g0846c-f7
                                                         1Gb(256MB) (16M x 8 bit x 8 bank) DDR3 parts, the column address width = 10 and
                                                         the device row address width = 14b.  The single x8bit device contains 128MB, and
                                                         requires TWO such parts to populate the DFM 16b DDR3 interface. This then yields
                                                         a total rank size = 256MB = 2^28.
                                                         For a single-rank configuration (RANK_ENA=0), SW would program PBANK_LSB>=3 to
                                                         select mem_adr[x] bits above the legal DFM address range for mem_adr[27:0]=256MB.
                                                         For a dual-rank configuration (RANK_ENA=1), SW would program PBANK_LSB=4 to select
                                                         rank=mem_adr[28] as the bit used to determine which 256MB rank (of 512MB total) to
                                                         access (via rank chip enables - see: DFM DDR3 CS0[1:0] pins for connection to

 * DLL Bringup sequence:

 * 2. Write 1 to DFM_DLL_CTL2[DLL_BRINGUP]
 * 3. Wait for 10 FCLK cycles, then write 1 to DFM_DLL_CTL2[QUAD_DLL_ENA]. It may not be feasible to count 10 FCLK cycles, but the
 *    idea is to configure the delay line into DLL mode by asserting DLL_BRING_UP earlier than [QUAD_DLL_ENA], even if it is one
 *    cycle early. DFM_DLL_CTL2[QUAD_DLL_ENA] must not change after this point without restarting the DFM and/or DRESET initialization
 *    sequence.
 * 4. Read L2D_BST0 and wait for the result. (L2D_BST0 is subject to change depending on how it called in o63. It is still ok to go
 *    without step 4, since step 5 has enough time)
 * 5. Wait 10 us.
 * 6. Write 0 to DFM_DLL_CTL2[DLL_BRINGUP]. DFM_DLL_CTL2[DLL_BRINGUP] must not change after this point without restarting the DFM
 *    and/or DRESET initialization sequence.
 * 7. Read L2D_BST0 and wait for the result. (same as step 4, but the idea here is the wait some time before going to step 8, even it
 *    is one cycle is fine)
 * 8. Write 0 to DFM_DLL_CTL2[DRESET].  DFM_DLL_CTL2[DRESET] must not change after this point without restarting the DFM and/or

/**
 * cvmx_dfm_rodt_mask
 *
 * DFM_RODT_MASK = DFM Read OnDieTermination mask
 * System designers may desire to terminate DQ/DQS/DM lines for higher frequency DDR operations
 * especially on a multi-rank system. DDR3 DQ/DM/DQS I/O's have built in
 * Termination resistor that can be turned on or off by the controller, after meeting tAOND and tAOF
 * timing requirements. Each Rank has its own ODT pin that fans out to all the memory parts
 * in that rank. System designers may prefer different combinations of ODT ON's for reads
 * into different ranks. Octeon supports full programmability by way of the mask register below.
 * Each Rank position has its own 8-bit programmable field.
 * When the controller does a read to that rank, it sets the 4 ODT pins to the MASK pins below.
 * For eg., When doing a read into Rank0, a system designer may desire to terminate the lines
 * with the resistor on Dimm0/Rank1. The mask RODT_D0_R0 would then be [00000010].
 * Octeon drives the appropriate mask values on the ODT pins by default. If this feature is not
 * required, write 0 in this register. Note that, as per the DDR3 specifications, the ODT pin
 * for the rank that is being read should always be 0.
 *
 * Notes:
 * - Notice that when there is only one rank, all valid fields must be zero.  This is because there is no
 * "other" rank to terminate lines for.  Read ODT is meant for multirank systems.
 * - For a two rank system and a read op to rank0: use RODT_D0_R0<1> to terminate lines on rank1.
 * - For a two rank system and a read op to rank1: use RODT_D0_R1<0> to terminate lines on rank0.
 * - Therefore, when a given RANK is selected, the RODT mask for that RANK is used.
 *
 * DFM always reads 128-bit words independently via one read CAS operation per word.
 * When a RODT mask bit is set, DFM asserts the OCTEON ODT output
 * pin(s) starting (CL - CWL) CK's after the read CAS operation. Then, OCTEON
 * normally continues to assert the ODT output pin(s) for 5+DFM_CONTROL[RODT_BPRCH] more CK's
 * - for a total of 6+DFM_CONTROL[RODT_BPRCH] CK's for the entire 128-bit read -
 * satisfying the 6 CK DDR3 ODTH8 requirements.
 *
 * But it is possible for OCTEON to issue two 128-bit reads separated by as few as
 * RtR = 4 or 5 (6 if DFM_CONTROL[RODT_BPRCH]=1) CK's. In that case, OCTEON asserts the ODT output pin(s)
 * for the RODT mask of the first 128-bit read for RtR CK's, then asserts
 * the ODT output pin(s) for the RODT mask of the second 128-bit read for 6+DFM_CONTROL[RODT_BPRCH] CK's
 * (or less if a third 128-bit read follows within 4 or 5 (or 6) CK's of this second 128-bit read).
 * Note that it may be necessary to force DFM to space back-to-back 128-bit reads
 * to different ranks apart by at least 6+DFM_CONTROL[RODT_BPRCH] CK's to prevent DDR3 ODTH8 violations.

 *
 * Deskew setting is measured in units of 1/8 FCLK, so the above BYTE* values can range over 4 FCLKs.
 *
 * Assuming DFM_WLEVEL_CTL[SSET]=0, the BYTE*<2:0> values are not used during write-leveling, and
 * they are over-written by the hardware as part of the write-leveling sequence. (HW sets STATUS==3
 * after HW write-leveling completes for the rank). SW needs to set BYTE*<4:3> bits.
 *
 * Each CSR may also be written by SW, but not while a write-leveling sequence is in progress. (HW sets STATUS==1 after a CSR write.)
 *
 * SW initiates a HW write-leveling sequence by programming DFM_WLEVEL_CTL and writing RANKMASK and INIT_START=1 with SEQUENCE=6 in DFM_CONFIG.
 * DFM will then step through and accumulate write leveling results for 8 unique delay settings (twice), starting at a delay of
 * DFM_WLEVEL_RANKn[BYTE*<4:3>]*8 CK increasing by 1/8 CK each setting. HW will then set DFM_WLEVEL_RANKn[BYTE*<2:0>] to indicate the
 * first write leveling result of '1' that followed a reslt of '0' during the sequence by searching for a '1100' pattern in the generated
 * bitmask, except that DFM will always write DFM_WLEVEL_RANKn[BYTE*<0>]=0. If HW is unable to find a match for a '1100' pattern, then HW will
 * set DFM_WLEVEL_RANKn[BYTE*<2:0>] to 4.

 *
 * DFM_WODT_MASK = DFM Write OnDieTermination mask
 * System designers may desire to terminate DQ/DQS/DM lines for higher frequency DDR operations
 * especially on a multi-rank system. DDR3 DQ/DM/DQS I/O's have built in
 * Termination resistor that can be turned on or off by the controller, after meeting tAOND and tAOF
 * timing requirements. Each Rank has its own ODT pin that fans out to all the memory parts
 * in that rank. System designers may prefer different combinations of ODT ON's for writes
 * into different ranks. Octeon supports full programmability by way of the mask register below.
 * Each Rank position has its own 8-bit programmable field.
 * When the controller does a write to that rank, it sets the 4 ODT pins to the MASK pins below.
 * For eg., When doing a write into Rank0, a system designer may desire to terminate the lines
 * with the resistor on Dimm0/Rank1. The mask WODT_D0_R0 would then be [00000010].
 * Octeon drives the appropriate mask values on the ODT pins by default. If this feature is not
 * required, write 0 in this register.
 *
 * Notes:
 * - DFM_WODT_MASK functions a little differently than DFM_RODT_MASK.  While, in DFM_RODT_MASK, the other
 * rank(s) are ODT-ed, in DFM_WODT_MASK, the rank in which the write CAS is issued can be ODT-ed as well.
 * - For a two rank system and a write op to rank0: use RODT_D0_R0<1:0> to terminate lines on rank1 and/or rank0.
 * - For a two rank system and a write op to rank1: use RODT_D0_R1<1:0> to terminate lines on rank1 and/or rank0.
 * - When a given RANK is selected, the WODT mask for that RANK is used.
 *
 * DFM always writes 128-bit words independently via one write CAS operation per word.
 * When a WODT mask bit is set, DFM asserts the OCTEON ODT output pin(s) starting the same cycle
 * as the write CAS operation. Then, OCTEON normally continues to assert the ODT output pin(s) for five
 * more cycles - for a total of 6 cycles for the entire word write - satisfying the 6 cycle DDR3
 * ODTH8 requirements. But it is possible for DFM to issue two word writes  separated by as few
 * as WtW = 4 or 5 cycles. In that case, DFM asserts the ODT output pin(s) for the WODT mask of the
 * first word write for WtW cycles, then asserts the ODT output pin(s) for the WODT mask of the
 * second write for 6 cycles (or less if a third word write follows within 4 or 5
 * cycles of this second word write). Note that it may be necessary to force DFM to space back-to-back
 * word writes to different ranks apart by at least 6 cycles to prevent DDR3 ODTH8 violations.
