Add the Sansa M200 (v1) as a target - it's extremely similar to the Logik DAX (the LCD driver worked unchanged). Plus various tcc77x work, including a working tick interrupt (enabled in the bootloader). Rockbox itself builds for the M200 (there are no keymaps yet for the DAX), but doesn't progress very far due to the lack of an ATA (NAND flash) driver.
