2 * Neuros Technologies OSD2 board support
3 *
4 * Modified from original 644X-EVM board support.
5 * 2008 (c) Neuros Technology, LLC.
6 * 2009 (c) Jorge Luis Zapata Muga <jorgeluis.zapata@gmail.com>
7 * 2009 (c) Andrey A. Porodko <Andrey.Porodko@gmail.com>
8 *
9 * The Neuros OSD 2.0 is the hardware component of the Neuros Open
10 * Internet Television Platform. Hardware is very close to TI
11 * DM644X-EVM board. It has:
12 * DM6446M02 module with 256MB NAND, 256MB RAM, TLV320AIC32 AIC,
13 * USB, Ethernet, SD/MMC, UART, THS8200, TVP7000 for video.
14 * Additionaly realtime clock, IR remote control receiver,
15 * IR Blaster based on MSP430 (firmware although is different
16 * from used in DM644X-EVM), internal ATA-6 3.5” HDD drive
17 * with PATA interface, two muxed red-green leds.
18 *
