From e9489e7f7bdf45edb5e274c6b771485532ea906c Mon Sep 17 00:00:00 2001 From: Dan Crowell Date: Tue, 30 May 2017 15:32:26 -0500 Subject: Use XSCOM BAR from Bootloader instead of hardcoded value The memory map can be modified by the SBE such that the XSCOM BAR is not in the default location. The BAR value is passed up through the bootloader into hostboot.
