[PATCH 0/9] bus: brcmstb_gisb: add support for GISBv7 arbiter

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 three 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.
