[edk2-devel] [PATCH edk2-platforms 1/1] Silicon/NXP: LX2160A: Add SerDes Support
Wasim Khan
wasim.khan at oss.nxp.com
Tue Jun 9 21:08:54 UTC 2020
From: Wasim Khan <wasim.khan at nxp.com>
Based on SerDes protocol value in reset configuration word (RCW)
different IP blocks gets enabled in HW.
Add SoC specific SerDes configuration for LX2160A, which can be
used by different IPs to know the enabled interfaces and perform
the required initialization.
