drivers: add irq interrupt framework support This patch add support for IRQ interrupt, FIQ not included. It will be enabled when you select CONFIG_GICV2 or CONFIG_GICV3. The framework support gic interrupt and gpio interrupt, relative APIs are provided in: ./include/irq-platform.h If you'd like to add a new platform support into interrupt framework, please follow the steps: 1. add relative definitions in the file like other platforms: ./include/irq-platform.h 2. add GICD, GICC and GICR(for GICV3) base address definitions in the rkxxx-common.h, they are needed in: arch/arm/cpu/armv8/start.S; 3. enable CONFIG_GICV2 or CONFIG_GICV3. Notice: 1. the framework is initialize in function 'interrupt_init()' of _sequence_r[]. So you should not request irqs too early. 2. IRQ stack size is configured by CONFIG_IRQ_STACK_SIZE, the default value is 8KB when CONFIG_IRQ_STACK_SIZE is absent.
