- * xip_irqpending()
- *
- * return non zero when any hardware interrupt is pending.
- *
- * xip_currtime()
- *
- * return a platform specific time reference to be used with
- * xip_elapsed_since().
- *
- * xip_elapsed_since(x)
- *
- * return in usecs the elapsed timebetween now and the reference x as
- * returned by xip_currtime().
- *
- * note 1: conversion to usec can be approximated, as long as the
- * returned value is <= the real elapsed time.
- * note 2: this should be able to cope with a few seconds without
- * overflowing.

- * xip_iprefetch()
- *
- * Macro to fill instruction prefetch
- * e.g. a series of nops: asm volatile (".rep 8; nop; .endr");
