RTEMS on Beaglebone Black

Have you got interrupts working on the GPIOs. Also, do you have any 
sample of reading and writing to GPIO. I need to see whether it is going 
to be fast enough,

I ran a program (on linux) on beagle that used registers basically 
toggling an output. EG

It toggled at rate of just under 1Mhz, and what was just doing a while 1 
loop. I did not look even look at interrupts there and did nothing else 
- I didn't even do any reads of GPIO.

I want to get interrupts happening at 1.56Mhz (preferable) and read 14 
GPOI, sbut I could go to half the rate by reducing my sample rate.  The 
beagle runs at 1Ghz, so I think it should be able to handle it.
