* The ATSTK1006 daughterboard is very similar to the ATSTK1002. Both
* have the AT32AP7000 chip on board; the difference is that the
* STK1006 has 128 MB SDRAM (the STK1002 uses the 8 MB SDRAM chip on
* the STK1000 motherboard) and 256 MB NAND flash (the STK1002 has
* none.)
*
* The RAM difference is handled by the boot loader, so the only
* difference we end up handling here is the NAND flash.
