[Skyeye-developer] help simulating at91 timer

[Michael.Kang]

            In the original implementation of at91 simulation, only
timer1 is simulated. I had done a patch against skyeye_1_2_3_Rel to
implement three timer channel.Maybe useful for your case.
         Run "patch -p0 <  skyeye_mach_at91-timer.diff" under skyeye
source dir to apply my patch in the attachment.
