coool, this does not surprise me.  i mean if you think about it, AT
Bus, FlexBus, PCIe, all of these are dynamic memory-mapped
peripherals, so there's no reason why DRAM (or SDRAM) should not also
be dynamic.

each wishbone peripheral would need to come back with an answer at the
physical bus level as to whether the read/write had succeeded.
