 * Write to target memory using the virtual address.
 *
 * Note that this fn is used to implement software breakpoints. Targets
 * can implement support for software breakpoints to memory marked as read
 * only by making this fn write to ram even if it is read only(MMU or
 * MPUs).
 *
 * It is sufficient to implement for writing a single word(16 or 32 in
 * ARM32/16 bit case) to write the breakpoint to ram.
 *
 * The target should also take care of "other things" to make sure that
 * software breakpoints can be written using this function. E.g.
 * when there is a separate instruction and data cache, this fn must
 * make sure that the instruction cache is synced up to the potential
 * code change that can happen as a result of the memory write(typically
 * by invalidating the cache).
 *
 * The high level wrapper fn in target.c will break down this memory write
 * request to multiple write requests to the target driver to e.g. guarantee
 * that writing 4 bytes to an aligned address happens with a single 32 bit
 * write operation, thus making this fn suitable to e.g. write to special
 * peripheral registers which do not support byte operations.
