rtai 3.1 on xscale

[Stefan Frank]

Hello Chris

Our patch is available by

http://iserver.hta.fhz.ch/~l4i/trizeps2/pxa255_2.6.9-trizeps2-fks.patch

Give it a try, if you encounter some problem please mail back to the mailing 
list. By the way, you have to use the vulcano branch of RTAI, it is meant to 
be the one for ARM.

Some points you have to apply:
- Adeos support in kernel has to be configured as a module
- you have to configure RTAI for immediate dispatching (look at 
README.INSTALL).
- we had to fix some things in RTAI to get it running, if you encounter some 
problems we could compare the errors

Probably there are other things I forget now ;).

Good luck

Stefan
