Well, irqloop is preconfigured for boring x86 PCs, not thrilling PowerPC
platforms :). It assumes there is a 16550-based UART at the given
address using the given IRQ, but I would bet this doesn't apply to your
board. Please check doc/txt/irqbench.txt on the requirements.
What interface do you plan to use for the IRQ latency test? Maybe it is
possible to extend the benchmark driver.
