[PATCH v1 5/8] platform/x86: intel/pmc: Relocate Ice Lake PCH support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Xi Pardee <xi.pardee@xxxxxxxxx>

Create icl.c for Ice Lake PCH specific structures and init().
This file supports Ice Lake, Ice Lake NNPI and Jasper Lake platforms.
There are no functional changes involved.
