Currently - jedec.c does this atleast - if different write functions
do different things, that should be fixed (make them all do the same)
- again @work and dont have the time to check, but:
* Verifies erase
* Writes each page, verifying each page after writing
... then you do a -v after that and youll end up near-triple-verifying
stuff -- ok it's nice to be sure, but that's not very speedy, but ok
for on-motherboard flashing.
I suggest that we have it like this:
-e erases and verifies erase
-w erases, writes (verifying each page...) and verifies write (as in
with -wv now)
Then i suggest we have some flag to disable all verifies (including
the one in jedec.c checking each page write) in case one is using a
slow external programmer. -n maybe (as in --no-verify)?
