thinko ... this loops forever.  the tested fix:
	j = flashes[i].shift;
	while (--j >= 0)
		if (idcode[j] != 0x7f)
			break;

this whole change increases code size a bit (20 - 60 bytes on Blackfin 
depending on how many flashes are supported), but it makes management easier 
and allows for arbitrarily long manufacturers ids.  so i think it's worth it.
