Re: Atlas support.

[Carsten Langgaard <carstenl@mips.com>]

If you don't know what you are doing it is not that simple to get Atlas
support in the 2.2.14 kernel.
It will probably take me a couple of days, but I'm afraid I don't have the
time.
Right now I'm in the progress of integrating our 2.2.12 work into the 2.4.0
kernel.
I have already sent Ralf a patch, so one can run the 2.4.0 kernel on the
Atlas board with a QED, but I don't think he had committed it yet.

I hope to have a new patch with FP emulator integrated for the 2.4.0 kernel
ready in next week, if time permits it.
