There was already a PLATFORM_NR_IRQS define, which is now accompanied by a VARIANT_NR_IRQS. To be able to initialize these interrupts, init_IRQ now calls a variant specific hook. Changes compared to v1: - adapted to new CONFIG_VARIANT_IRQ_EXT - removed definition and call of platform_init_IRQ as there already is a platform_init_irq defined in asm/platform.h with a weak default in kernel/platform.c - renamed variant_init_IRQ to variant_init_irq Note that I could not find the call site of platform_init_irq although it is stated in platform.h that it is called from init_IRQ.
