+ * 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
