Tejun and all -

I have a new log - I got somewhat further by setting this bit when 
init'd via HOST_CTRL:

Bit [28]: PERR Rpt Dsbl (R/W) – PERR Report Disable. This bit, when set 
to one, disables reporting of PCI bus
parity errors to the Command Execution State Machine (such errors would 
otherwise cause the state machine to stop
and report an error in the Command Error register).

This causes the PMP device to be noticed, but the first qc command never 
completes.

Please see the log and see if there is anything obvious.

Thanks,

...tom
