[OpenPower-Firmware] Problem with CCS

[Krystian Hebel]

(Sending again, first mail was bounced off, sorry if someone receives 
this for a second time)

Thanks, I wish I knew about this earlier, this is indeed a great aid in 
debugging. It is even worth waiting for a couple of hours to (re)build 
the image :)

As for my problem, it is solved now. The immediate cause was bad global 
PHY offset in RC_CONFIG0 register. I tried to get fancy and hardcode 
values from talos-MEMD.tvpd before we had implemented VPD parser and I 
must have downloaded wrong file, as the values in it don't make sense. 
Now I can't even find the exact version of file in repository, so 
probably I accidentally overwrote it with garbage.

Thank you again, this definitely pushed us forward.
