SMP ABUS -- use pattern A to detect lane failures
p9_io_obus_linktrain
- Prior to engaging link training, send and observe pattern A in PHY
RX capture latches
- Power down any failed lanes, with sparing for single lane failures or
deconfiguration for multi-lane failures to be handled by DL training
in downstream HWP code
- Adapt flow so HWP is directly callable in CCM retraining flow
p9_io_obus_dccal
- Reset attributes used by p9_io_obus_linktrain -- needed to support
reconfig loop IPL and CCM retraining flow
p9_fab_iovalid
- Update DL state machine half link fail detection logic
p9_io_obus_attributes
- Create new attributes to support pattern A detection scheme
ATTR_IO_OBUS_PAT_A_DETECT_RUN - flag to track per half link status, ised
to enable coordinated execution on endpoints
without requiring HWP interface changes
ATTR_IO_OBUS_PAT_A_DETECT_RX_AMP_VALUE - RX amp bias, override only
ATTR_IO_OBUS_PAT_A_CAPTURE - actual RX data pipe content, for debug
ATTR_IO_OBUS_LANE_PDWN - actual per-lane powerdown decisions, for debug
