[LinuxBIOS] Nvidia MCP55 support

[Lu, Yinghai]

I'm working on MCP55 support. There is some blank in
mcp55_early_setup.c, So Current Only IDE and USB are working but the
sata/nic/pcie don't work.

There is another option is use Nvidia binary code (NVMM) directly.

So questions is

nvidia would allow AMD to release NVMM binary to LinuxBIOS. .., Is it ok
to LinuxBIOS? Does is voliatiote the GPL?. Because this code will be
called by LinuxBIOS. And it is not loaded and started by LinuxBIOS. (cpu
microcode patch code and scsi firmare is loaded and started by LinuxBIOS
but setting some register).

Is VSM loaded and started only for OLPC?

Thanks

Yinghai Lu
