[U-Boot] [PATCH 10/11] powerpc/corenet2: Add SerDes for corenet2
York Sun
yorksun at freescale.com
Fri Aug 17 20:27:22 CEST 2012
Create new files to handle 2nd generation Chassis as the registers are
organized differently.
- Add SerDes protocol parsing and detection
- Add support of 4 SerDes
- Add CPRI protocol in fsl_serdes.h
The Common Public Radio Interface (CPRI) is publicly available
specification that standardizes the protocol interface between the
radio equipment control (REC) and the radio equipment (RE) in wireless
basestations. This allows interoperability of equipment from different
vendors,and preserves the software investment made by wireless service
providers.
