Well the Mavell SoC has two free timers already on board, "Timer 0 is used as
free-running clocksource, while timer 1 is used as clock_event_device.";
lurks in arch/arm/plat-orion/time.c. It seems to have a nanosecond
resolution[1] as TCLK is 166Mhz...
This is all in addition to the microsecond timer TS seem to supply, this of
course assumes I know what I'm talking about but thats my reading of the
thing.

Well I was thinking about this. If I *really* grovel to TS, NDA myself till
I suffocate they might be open to the idea that I use all that userland API
stuff that is now in 2.6. So the 'secret' stuff is in userspace where it
should be whilst the rest of us can continue to use a regular kernel. Of
course the advantage being that once it's cooked, the private secret userland
stuff should never need even recompiling; statically link the thing against
uclibc and produce one for EABI and one for OABI.
Obviously I would have to speak to them and I'm 99.9% sure they are going to
tell me where to shove the suggestions but hey, the time wasted at my end
would be an email.

Most it was done by the already 'orion5x' folk, I just attached the hooks :)
Thanks though, its been a learning experience, shame as in the end all I will
be doing is using my TS-7800 as a home xDSL router :) Maybe I'll use the LCD
to show the local train station timetable though...
Cheers
