This patch set contains changes to enable the GISB arbiter driver on the latest ARM64 architecture Set-Top Box chips from Broadcom. This driver relies on being able to hook the abort handlers of the processor core that are triggered by bus error signals generated by the GISB bus arbiter hardware found in BCM7XXX chips. The first two patches are based on the arm64/for-next/core branch to enable this functionality for the arm64 architecture. The remaining patches correct some issues with the existing driver, add the ARM64 architecture specific support to the driver, and finally add the new register map for the GISBv7 hardware first appearing in the BCM7278 device. Changes since v1 at [1]: - Removed code associated with hooking SError handling in favor of a registered notifier (Thanks Mark!) - Removed an unnecessary explicit cast (Thanks Gregory!)
