the following patch was just integrated into master: commit 4a666423c6d71614b7c2b539afa33d823c1896d5 Author: Martin Roth <martinroth@google.com> Date: Tue Aug 25 17:04:59 2015 -0600 northbridge/intel/gm45/Kconfig: Remove IOMMU symbol choice In the gm45 code, IOMMU is always selected to be enabled. Instead this patch removes the Kconfig symbol and its dependencies. This leads to the same effect without the need for the symbol. The symbol is still used in the K8 code as it's not selected, simply defaulted to being enabled, and one of the mainboards disables it.
