No. I can't remember why in this decongestant-drugged state that I'm in
*wheezes loudly*, but I remember that it doesn't. Some quirk that the PXA
does. Check my debrick code in cvs:

Look at the programflash() code in there to see how I do it.

Then that'll shift over addresses that aren't unlock, which is definately not
what I want.

For what it's worth, when I added shift code to jedec_probe, that seemed to
work, however at some point my unlock addresses are getting reset (?!!?!) to
555/2aa, instead of 555<<1/2aa<<1. I should probably debug that.
