Re: ARM8 / BCM2837 & Raspbian

It is not that much, it is just a matter of the patch. For the rest uou 
should know that RTAI has some ARM support already.
I forgot a lot about ARM but I do know that we had a first, kernel only, 
por, patch development included, made by two students many many years ago.
That said I'm not saying that it is a downhill work, I know it requires 
some difficult climbing, but is just a matter of willingness and time. 
There is nothing new to invent.
