From 87543425d7734099aed6c1def595ee4d710d6ce0 Mon Sep 17 00:00:00 2001 From: Bruce Griffith Date: Mon, 8 Dec 2014 01:43:23 -0700 Subject: AMD 00730F01: Topology changes required by KaveriPI v1.1.0.7 update The updated KaveriPI binary, upgrading to v1.1.0.7, requires changes to define the PSP device (PCI 0:08.0) and the IOMMU device (PCI 0:00.2). In the new AGESA binary, the IOMMU device is enabled and must be disabled in devicetree.cb and agesawrapper_amdinitenv() to maintain the same level of functionality.
