freebsd-skq/sys/contrib/octeon-sdk/cvmx-lmcx-defs.h
Juli Mallett dc4ee6ca91 Merge the Cavium Octeon SDK 2.3.0 Simple Executive code and update FreeBSD to 
make use of it where possible.

This primarily brings in support for newer hardware, and FreeBSD is not yet
able to support the abundance of IRQs on new hardware and many features in the
Ethernet driver.

Because of the changes to IRQs in the Simple Executive, we have to maintain our
own list of Octeon IRQs now, which probably can be pared-down and be specific
to the CIU interrupt unit soon, and when other interrupt mechanisms are added
they can maintain their own definitions.

Remove unmasking of interrupts from within the UART device now that the
function used is no longer present in the Simple Executive.  The unmasking
seems to have been gratuitous as this is more properly handled by the buses
above the UART device, and seems to work on that basis.

Encoding used to determine which memory address
bit position represents the low order DDR ROW address.
The processor's memory address[34:7] needs to be

and that is a function of the following:
1. Datapath Width (64 or 32)
2. \# Banks (8)
3. \# Column Bits of the memory part - spec'd indirectly

4. \# Row Bits of the memory part - spec'd indirectly

Col Address starts from mem_addr[2] for 32b (4Bytes)
dq width or from mem_addr[3] for 64b (8Bytes) dq width
\# col + \# bank = 12. Hence row_lsb is mem_adr[15] for

* cvmx_lmc#_delay_cfg
*
* LMC_DELAY_CFG = Open-loop delay line settings
*
*
* 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

* cvmx_lmc#_rodt_mask
*
* LMC_RODT_MASK = LMC Read OnDieTermination mask
* System designers may desire to terminate DQ/DQS lines for higher frequency DDR operations
* especially on a multi-rank system. DDR3 DQ/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 DIMM. 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 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.

*
* 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

*
* 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_WODT_CTL1 = LMC Write OnDieTermination control
* System designers may desire to terminate DQ/DQS/DM lines for higher frequency DDR operations
* (667MHz and faster), especially on a multi-rank system. DDR2 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 DIMM. System designers may prefer different combinations of ODT ON's for read and write
* 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 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
* writing 0 in QS_DIC. Octeon drives the appropriate mask values on the ODT pins by default.
* If this feature is not required, write 0 in this register.
*

*
* LMC_WODT_MASK = LMC Write OnDieTermination mask
* System designers may desire to terminate DQ/DQS lines for higher frequency DDR operations
* especially on a multi-rank system. DDR3 DQ/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 DIMM. 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:
* When a given RANK is selected, the WODT mask for that RANK is used. The resulting WODT 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 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.
