Makes sense. Oh well, I guess this is just going to have to be a target variant specific flash algorithm. Still if I can keep the flash access separate from the flash programming algorithm then maybe it can be reused with different flash access definitions? Just a wild thought. I'll have to dig into the OpenOCD code to see if this is workable.
