To provide the kernel with the proper information, prepare the existing model .dts to be split up and eventually create a new .dts file which can be used to boot a kernel using the GICv3 in the model. Patch 1/4 changes the common device tree to allow sharing most of the definitions later, while patch 2/4 is a drive-by-fix to add support for the recently enabled EOImode=1. Patch 3/4 splits the existing DT up to have a common .dtsi file and a stub foundation-v8.dts in preparation for the final patch 4/4, which adds a new foundation-v8-gicv3.dts that has the required GICv3 node. Together with the GICv3 support of the bootwrapper this allows to boot Linux and make it use the GICv3 interrupt controller. Cheers, Andre.
