Just because I write the patches doesn't mean they get accepted.  They
need to be acked by someone who has tested them first.  I'm offering
to take on the workload of writing the patches, but I cannot take on
the testing.  A number of the changes that I'm making right now (not
just DataFlash) affect every single board, but I cannot test them all.
 Best I can do is make sure it works on the handful of boards I do
have, post the patches for others to test, and only request inclusion
in mainline when nobody reports problems with them.

The mods I'm interested in are the architectural changes which I can
and will test.  The DataFlash changes are collateral damage.  The
alternative for me is to break dataflash support without even
attempting to providing a solution.

Then how does *anybody* attempt to fix common code?  Nobody can test
all platforms.
