*
* Notes:
* The DQ bits add OUTGOING delay only to dq, dqs_[p,n], cb, cbs_[p,n], dqm. Delay is approximately
* 50-80ps per setting depending on process/voltage. There is no need to add incoming delay since by
* default all strobe bits are delayed internally by 90 degrees (as was always the case in previous
* passes and past chips.
*
* The CMD add delay to all command bits DDR_RAS, DDR_CAS, DDR_A<15:0>, DDR_BA<2:0>, DDR_n_CS<1:0>_L,
* DDR_WE, DDR_CKE and DDR_ODT_<7:0>. Again, delay is 50-80ps per tap.
*
* The CLK bits add delay to all clock signals DDR_CK_<5:0>_P and DDR_CK_<5:0>_N. Again, delay is
* 50-80ps per tap.
*
* The usage scenario is the following: There is too much delay on command signals and setup on command
* is not met. The user can then delay the clock until setup is met.
*
* At the same time though, dq/dqs should be delayed because there is also a DDR spec tying dqs with
* clock. If clock is too much delayed with respect to dqs, writes will start to fail.
*
* This scheme should eliminate the board need of adding routing delay to clock signals to make high
* frequencies work.

1. \# Banks (4 or 8) - spec'd by BANK8

* 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 from 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:
* When a given RANK is selected, the RODT mask for that RANK is used. The resulting RODT mask is
* driven to the DIMMs in the following manner:
* RANK_ENA=1 RANK_ENA=0
* Mask[3] -> DIMM1_ODT_1 MBZ
* Mask[2] -> DIMM1_ODT_0 DIMM1_ODT_0
* Mask[1] -> DIMM0_ODT_1 MBZ
* Mask[0] -> DIMM0_ODT_0 DIMM0_ODT_0
*
* LMC always reads entire cache blocks and always reads them via two consecutive
* read CAS operations to the same rank+bank+row spaced exactly 4 CK's apart.
* When a RODT mask bit is set, LMC asserts the OCTEON ODT output
* pin(s) starting (CL - CWL) CK's after the first read CAS operation. Then, OCTEON
* normally continues to assert the ODT output pin(s) for 9+LMC*_CONTROL[RODT_BPRCH] more CK's
* - for a total of 10+LMC*_CONTROL[RODT_BPRCH] CK's for the entire cache block read -
* through the second read CAS operation of the cache block,
* satisfying the 6 CK DDR3 ODTH8 requirements.
* But it is possible for OCTEON to issue two cache block reads separated by as few as
* RtR = 8 or 9 (10 if LMC*_CONTROL[RODT_BPRCH]=1) CK's. In that case, OCTEON asserts the ODT output pin(s)
* for the RODT mask of the first cache block read for RtR CK's, then asserts
* the ODT output pin(s) for the RODT mask of the second cache block read for 10+LMC*_CONTROL[RODT_BPRCH] CK's
* (or less if a third cache block read follows within 8 or 9 (or 10) CK's of this second cache block read).
* Note that it may be necessary to force LMC to space back-to-back cache block reads
* to different ranks apart by at least 10+LMC*_CONTROL[RODT_BPRCH] CK's to prevent DDR3 ODTH8 violations.

* This is four CSRs per LMC, one per each rank.
*
* Deskew setting is measured in units of 1/8 CK, so the above BYTE* values can range over 4 CKs.
*
* Assuming LMC*_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 LMC*_WLEVEL_CTL and writing RANKMASK and INIT_START=1 with SEQUENCE=6 in LMC*_CONFIG.
* LMC will then step through and accumulate write leveling results for 8 unique delay settings (twice), starting at a delay of
* LMC*_WLEVEL_RANKn[BYTE*<4:3>]*8 CK increasing by 1/8 CK each setting. HW will then set LMC*_WLEVEL_RANKi[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 LMC will always write LMC*_WLEVEL_RANKi[BYTE*<0>]=0. If HW is unable to find a match for a '1100' pattern, then HW will
* set LMC*_WLEVEL_RANKi[BYTE*<2:0>] to 4.
* See LMC*_WLEVEL_CTL.
*
* LMC*_WLEVEL_RANKi values for ranks i without attached DRAM should be set such that
* they do not increase the range of possible BYTE values for any byte
* lane. The easiest way to do this is to set
* LMC*_WLEVEL_RANKi = LMC*_WLEVEL_RANKj,
* where j is some rank with attached DRAM whose LMC*_WLEVEL_RANKj is already fully initialized.

* Each Rank position has its own 8-bit programmable field.
* When the controller does a write to that rank, it sets the 8 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].
* If ODT feature is not desired, the DDR parts can be programmed to not look at these pins by

* System designers may desire to terminate DQ/DQS lines for higher frequency DDR operations

* 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

* Notes:

* RANK_ENA=1 RANK_ENA=0
* Mask[3] -> DIMM1_ODT_1 MBZ

* Mask[1] -> DIMM0_ODT_1 MBZ
* Mask[0] -> DIMM0_ODT_0 DIMM0_ODT_0
*
* LMC always writes entire cache blocks and always writes them via two consecutive
* write CAS operations to the same rank+bank+row spaced exactly 4 CK's apart.
* When a WODT mask bit is set, LMC asserts the OCTEON ODT output
* pin(s) starting the same CK as the first write CAS operation. Then, OCTEON
* normally continues to assert the ODT output pin(s) for 9+LMC*_CONTROL[WODT_BPRCH] more CK's
* - for a total of 10+LMC*_CONTROL[WODT_BPRCH] CK's for the entire cache block write -
* through the second write CAS operation of the cache block,
* satisfying the 6 CK DDR3 ODTH8 requirements.
* But it is possible for OCTEON to issue two cache block writes separated by as few as
* WtW = 8 or 9 (10 if LMC*_CONTROL[WODT_BPRCH]=1) CK's. In that case, OCTEON asserts the ODT output pin(s)
* for the WODT mask of the first cache block write for WtW CK's, then asserts
* the ODT output pin(s) for the WODT mask of the second cache block write for 10+LMC*_CONTROL[WODT_BPRCH] CK's
* (or less if a third cache block write follows within 8 or 9 (or 10) CK's of this second cache block write).
* Note that it may be necessary to force LMC to space back-to-back cache block writes
* to different ranks apart by at least 10+LMC*_CONTROL[WODT_BPRCH] CK's to prevent DDR3 ODTH8 violations.
