This series is a joint effort of Jian Luo jian.luo4@boschrexroth.de and Bin to support Intel TunnelCreek integrated graphics device (IGD).

It turns out that the bios emulator does not run the vbios correctly as there are smsw/rdmsr/wrmsr instructions in the vbios which are not emulated. Thus we only support running vbios with native mode.

Tested on Intel Crown Bay board with both SDVO interface (by Jian) and LVDS interface (by Bin) connected to the TunnelCreek IGD.

This series needs be applied after http://patchwork.ozlabs.org/patch/487473/.
