+config MXC_IRQ_PRIOR
+ bool "Use IRQ priority"
+ depends on ARCH_MXC
+ help
+ Select this if you want to use prioritized IRQ handling.
+ This feature prevents higher priority ISR to be interrupted
+ by lower priority IRQ even IRQF_DISABLED flag is not set.
+ This may be useful in embedded applications, where are strong
+ requirements for timing.
+ Say N here, unless you have a specialized requirement.
