I'm referring "QorIQ P2040 Reference Manual, Rev. 4, 6/2016" for bring up SRIO for P2040 Processor.

On page 1255 under chapter - "Serial RapidIO Interface", there is a point that states - "RapidIO endpoint cannot be configured as four 1x or two 2x ports".

Does this mean we cannot use "SerDes Protocol Select" bits as 0xF, which configures for two 2x ports?

Do we have to use some other protocol which configures for 4x operation, if we are to use SRIO?
