arm64: vexpress: Add dts files for the ARMv8 RTSM models This patch adds the DTS files for the ARMv8 RTSM and Foundation models. Signed-off-by: Pawel Moll <Pawel.Moll@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Acked-by: Arnd Bergmann <arnd@arndb.de>

arm64: dts: split Foundation model dts to put the GIC separately The ARMv8 Foundation model can be run with a GICv2 or a GICv3. To prepare for the GICv3 version of the .dts without code duplication, move most of the nodes of the existing DT (except the GIC) into an include file and just keep that include statement and the GIC node in the current foundation-v8.dts.

arm64: dts: Reserve the memory used for secondary CPU release address With the spin-table SMP booting method, secondary CPUs poll a location passed in the DT. The foundation-v8.dts file doesn't have this memory reserved and there is a risk of Linux using it before secondary CPUs are started. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

arm64: dts: prepare foundation-v8.dts to cope with GICv3 To prepare the ARM foundation model to support GICv3, we adjust the #address-cells property of the current GICv2 node to be compatible with the two cells required for GICv3 later.

arm64: dts: Foundation model: increase GICC region to allow EOImode=1 The Foundation model GIC mapping is wrong, as the GICC region should be 8kB instead of 4kB (the model implements the GICv2 architecture). This defect prevents the driver from switching to EOImode==1.
