This flash is like PMC model Pm39LV010 but capacity is 64kB.
Model ID was already defined, PREW works for me.

thanks for the patch!
applied with minor changes to the commit message in r1539.
the link to the datasheet got kicked because i dont think it makes a
lot of sense to link to sites that are easily replaceable with any
other hit by your favourite search engine.
