davinci: Initial support for Neuros OSD2 platform.
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.
