From 8aba24d3e12e5e65368c7c9c4bb6a37f6e7ec3c0 Mon Sep 17 00:00:00 2001 From: Lijian Zhao Date: Thu, 26 Oct 2017 12:16:53 -0700 Subject: soc/intel/apollolake: Switch to common p2sb Using common p2sb driver instead of private one. TEST=Boot up into OS, and read back registers through PCR by iotools, return is not 0xffffffff.
