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. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Shaohui Xie <b21989@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
