Florent Kermarrec 6017e7a763 phy/s7ddrphy: fix dqs_sys_latency for DDR2 2018-09-03 12:21:04 +02:00
Florent Kermarrec 7b427391bd phy/s7ddrphy: simplify cmd/dat phases computation and remove restrictions.
The real restrictions are:
- dat_phase = sys_latency*nphases - cas_latency (at least for writes, for read we can compensate that with bitslip)
- dat_phase != cmd_phase.
