568 * software breakpoints can be written using this function. E.g.
569 * when there is a separate instruction and data cache, this fn must
570 * make sure that the instruction cache is synced up to the potential
571 * code change that can happen as a result of the memory write(typically
572 * by invalidating the cache).
573 *
574 * The high level wrapper fn in target.c will break down this memory write
575 * request to multiple write requests to the target driver to e.g. guarantee
576 * that writing 4 bytes to an aligned address happens with a single 32 bit
577 * write operation, thus making this fn suitable to e.g. write to special
578 * peripheral registers which do not support byte operations.
