libflash/blocklevel: Extend the block level to be able to do ecc
At the moment ECC reads and writes are still being handled by the low level
core of libflash. ECC should be none of libflashes concern, it is primarily
a hardware access backend.
It makes sense for blocklevel to take care of ECC but currently it has no
way of knowing. With some simple modifications (which are rudimentary at
the moment and will need a performance improvement) blocklevel can handle
ECC, and with a little more effort this can be extended to provide read and
write protection in blocklevel.
