Kumar Gala - April 9, 2011, 6:47 p.m.
The P3041DS & P5020DS boards are almost identical (except for the
processor in them).  Additionally they are based on the P4080DS board
design so we use the some board code for all 3 boards.

Some ngPIXIS (FPGA) registers where reserved on P4080DS and now have
meaning on P3041DS/P5020DS.  We utilize some of these for SERDES clock
configuration.

Additionally, the P3041DS/P5020DS support NAND.
