+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.
