All the users of mx6q_4x_mt41j128.cfg (DDR3-1333H Micron MT41J128M16HA-15E or SK hynix H5TQ2G63BFR-H9C for i.MX6Q SABRE Lite, and DDR3-1600K Micron MT41K128M16JT-125:K for i.MX6 SABRE SD) support the optional down binning to DDR3-1066F (CL = 7, CWL = 6), which is possible at 532 MHz, so use it. In these conditions: tRCD(min) = 13.125 ns tRP(min) = 13.125 ns tRC(min) = max(tRAS(min, DDR3-1333H), tRAS(min, DDR3-1600K)) + tRP(min) tRAS(min, DDR3-1333H) = 36 ns tRAS(min, DDR3-1600K) = 35 ns MMDC1_MDCFG0.tCL should be set to 7 nCK, encoded as 0x4 in the bit-field MMDC1_MDCFG0[3:0]. MR0.CL should be set as in MMDC1_MDCFG0.tCL, i.e. to 7 nCK, which is encoded as 0x6 in MRS.LMR.MR0.{A6:A4, A2} and MMDC1_MDSCR[22:20, 18]. MMDC1_MDCFG1.tCWL should be set to 6 nCK, encoded as 0x4 in the bit-field MMDC1_MDCFG1[2:0]. MMDC1_MDCFG1.tRCD should be set to 13.125 ns, which is 7 nCK at 532 MHz, encoded as 0x6 in the bit-field MMDC1_MDCFG1[31:29]. MMDC1_MDCFG1.tRP should be set to 13.125 ns, which is 7 nCK at 532 MHz, encoded as 0x6 in the bit-field MMDC1_MDCFG1[28:26]. MMDC1_MDCFG1.tRC should be set to 49.125 ns, which is 27 nCK at 532 MHz, encoded as 0x1A in the bit-field MMDC1_MDCFG1[25:21]. Signed-off-by: Benoît Thébaudeau <benoit.thebaudeau@advansee.com>
