Initially I had the NAND layout defined in the DTS similar to
RaidSonic ICY BOX IB-NAS62x0, I removed it when I restarted my attempt
based strictly on the Dreamplug's implementation (which appears to
hang it's flash off SPI instead).  I'll re-add to the DTS and remove
the unused portion from the board file and see if that makes a
difference.  Thank you for the review, I should have results this
evening.
