From 901e43c90473e4acf950204abd55f0eb99bfee5b Mon Sep 17 00:00:00 2001 From: Andrey Petrov Date: Wed, 22 Jun 2016 19:22:30 -0700 Subject: drivers/intel/fsp2_0: Add simple reset handler Any FSP API call may request a reset. This is indicated in API function return code. Add trivial reset handler code.
