Yes, the PIXIS is generally register compatible across all boards.  =

may be some minor differences, but the OCM driver can work with all =

boards that have an PIXIS.

Is this true?  Don't we have pixis and ngpixis in u-boot?

Also you need "pixis" on MPC8544DS, MPC8572DS, MPC8536DS.

or FPGA not both.
