No. There is work doing by somebody from google or somewhere else, by
making mainline kernel work on Chromebook. Kernel 3.11 is the first
mainline kernel, that is able to boot and work on Chromebook. Working
parts is MMC controller, display controller, keyboard, etc. Not working
is usb, wifi, rtc, temperature sensors, etc.

By a tradition of open source, as I am interested, and I have experience
in kernel development, I have decided to debug wifi issue by myself. I
don't know, why I should port anything. Everything that was needed is
already ported - there is Chromebook device tree in kernel, there is all
required drivers. There is just a problem with powering up Marvell wifi
chip. I don't see, why fixing it requires any complex porting.

One thing worth doing is to compare 3.4 from chromeos and 3.4 mainline,
and find, if there any specific wifi changes. But there is possibly not.
