  SVN rev 218747 on 2011-02-16 20:07:44Z by adrian
  
  Modify the spi flash driver to allow smaller read IO sizes, but enforce
  the larger, aligned write+erase sizes the driver currently implements.
  
  This preserves write behaviour but makes the flash driver usable for things
  like a read-only FFS or a geom_uzip/geom_compress .
  
  Note that since GEOM will now return the sector size as being smaller,
  writes of sector size/alignment will now fail with an EIO. Code which
  writes to the flash device will have to be (for now) manually taught
  about the flash write blocksize.
