The following variants * GICv1 with Security Extensions, * GICv2 without Security Extensions, or * within Secure processor mode have the ability to assign group 0 or 1 to individual interrupts. Group 0 interrupts can be configured to raise an FIQ exception. This enables the use of NMIs with respect to RTEMS. BSPs can enable this feature with the BSP_ARM_GIC_ENABLE_FIQ_FOR_GROUP_0 define. Use arm_gic_irq_set_group() to change the group of an interrupt (default group is 1, if BSP_ARM_GIC_ENABLE_FIQ_FOR_GROUP_0 is defined).
