From e6f2f74b2977fd57f1133fdad182bb718e8b8ddc Mon Sep 17 00:00:00 2001 From: Lee Leahy Date: Thu, 21 Jul 2016 09:48:49 -0700 Subject: drivers/intel/fsp2_0: Add UPD display support Add UPD display support: * Add a Kconfig value to enable UPD value display * Add a routine to display a UPD value * Add a call before MemoryInit to display the UPD parameters * Add a routine to display the architectural parameters for MemoryInit * Add a weak routine to display the other UPD parameters for MemoryInit * Add a call before SiliconInit to display the UPD parameters * Add a weak routine to display the UPD parameters for SiliconInit TEST=Build and run on Galileo Gen2.
