[U-Boot-Users] How to add Timer Interrupt to u-boot?

As Jerry told you, U-Boot generally avoids using interrupts.  

For some architectures however we have code to allow using interrupts,
e.g. from standalone applications.  You can look at
examples/interrupt.c which effectively was written with
cpu/mpc5xxx/interrupts.c in mind.  The latter was of course derived
from the Linux version so it shouldn't be a big problem to do
something similar for other architectures.

Cheers

Once the  implementation is  up and running,  it is still a trick to keep it
running.  In a normal,  closed implementation,  this is not a problem;  in a
system with metaobject protocols [..] there is the potential for spectacular
failure modes if certain situations are not properly anticipated.
