From d1001e3f0ce0059a55a870c42bac8aba2e4befec Mon Sep 17 00:00:00 2001 From: York Sun Date: Mon, 8 Oct 2012 07:44:15 +0000 Subject: [PATCH] powerpc/corenet2: Add SerDes for corenet2 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.
