Besides the distributor and the CPU interface the GIC-400 additionally supports the virtual interface control blocks and the virtual CPU interfaces. Add the physical base addresses and size for these. See http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0471b/index.html -> 3.2. GIC-400 register map and Linux kernel's Documentation/devicetree/bindings/interrupt-controller/arm,gic.txt for more details. For the at GICH Virtual interface control blocks at 0xf1040000 cover the whole 128kB (0x20000) range.
