annotate packages/hal/arm/arch/current/include/hal_intr.h @ 3173:afb59e9b7339

* cdl/hal_arm.cdl: Add CDL to control whether both IRQs and FIQs are disabled in critical sections, or only IRQs. The default is to disable both and translate any FIQs into IRQs for delivery. The alternative is for FIQs to essentially exist outside eCos. * include/hal_arch.h (CPSR_THREAD_INITIAL): * include/hal_intr.h (CPSR_INTR_MASK, HAL_*_INTERRUPTS) (HAL_*_FIQ): Add definitions for separating FIQ from IRQ. * src/hal_mk_defs.c (main): * src/vectors.S (start, FIQ, IRQ, spurious_IRQ): (hal_*_interrupts, hal_*_FIQ, __fiq_stack_base): Add support for separating FIQ from IRQ in critical section processing.
