41 * The ATSTK1006 daughterboard is very similar to the ATSTK1002. Both
42 * have the AT32AP7000 chip on board; the difference is that the
43 * STK1006 has 128 MB SDRAM (the STK1002 uses the 8 MB SDRAM chip on
44 * the STK1000 motherboard) and 256 MB NAND flash (the STK1002 has
45 * none.)

47 * The RAM difference is handled by the boot loader, so the only
48 * difference we end up handling here is the NAND flash.
