 * versal: model enough of the Clock/Reset Low-power domain (CRL) to allow control of the Cortex-R5s
 * xlnx-zynqmp: Connect 4 TTC timers
 * exynos4210: Refactor GIC/combiner code to stop using qemu_split_irq
 * realview: replace 'qemu_split_irq' with 'TYPE_SPLIT_IRQ'
 * stellaris: replace 'qemu_split_irq' with 'TYPE_SPLIT_IRQ'
 * hw/core/irq: remove unused 'qemu_irq_split' function
 * npcm7xx: use symbolic constants for PWRON STRAP bit fields
 * virt: document impact of gic-version on max CPUs
