*
* 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.
* Additionally 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.
*
