 * The Neuros OSD 2.0 is the hardware component of the Neuros Open
 * Internet Television Platform. Hardware is very close to TI
 * DM644X-EVM board. It has:
 * 	DM6446M02 module with 256MB NAND, 256MB RAM, TLV320AIC32 AIC,
 * 	USB, Ethernet, SD/MMC, UART, THS8200, TVP7000 for video.
 * 	Additionaly realtime clock, IR remote control receiver,
 * 	IR Blaster based on MSP430 (firmware although is different
 * 	from used in DM644X-EVM), internal ATA-6 3.5” HDD drive
 * 	with PATA interface, two muxed red-green leds.
 *
