[meta-intel] Valleyisland graphics in Dora

Fri Apr 4 03:05:54 PDT 2014

Hi,

Any idea of the timeframe when the rt-support is coming? I have some time schedule pressure building up.. Current dora branch would be pretty much everything we need at the moment except the rt-support that is missing.

Oh the config-remove goes that easily. Yes, I know that if/when I go to change the configuration it's up to me to get it working, but that's okay. I'm making the build for very specific hardware so I can remove quite a much of drivers to save space and maybe make system startup bit faster.
