[Avila] recover entire flash image

[Tim Harvey]

You can also use jtag to pull off the entire image, although be prepared to let
it run overnight (very slow).  That's by far the simplest method.

Another method possibly requiring a little more work would be to use Tom's
method or a variation by booting a kernel/rfs via tftp that was setup to
configure the entire flash as a single mtd partition thus eliminating the need
to figure out where to pad the image.  You can do this by including certain mtd
modules and passing specific commandlines.  If this is too much for you resort
to the jtag method.
