From 0f593c22a8a88068ffdf73f87ee9ce98c343a977 Mon Sep 17 00:00:00 2001 From: Andrey Petrov Date: Fri, 17 Jun 2016 15:30:13 -0700 Subject: soc/intel/apollolake: Add utility functions for global reset Apollolake defines Global Reset where Host, TXE and PMC are reset. During boot we may need to trigger a global reset as part of platform initialization (or for error handling). Add functions to trigger global reset, enable/disable it and lock global reset bit.
