Regarding the RK3288, allow me to redirect your attention to a page on the archlinuxARM website:
The ASUS Chromebook Flip uses the RK3288 processor and has at least some degree of support on the Linux side or I don't think the ArchlinuxARM guys would have been able to support the platform. Anyhow, perhaps you guys can find out some useful info from the associated installation and wiki pages for this system.
