I have tested cache on OMAP3(Cortex-A8) and OMAP4(Cortex-A9). Why do you
think it's not working for you. Did you run some tests? If so, what was
the result? Are you enabling only L1 or both L1 & L2? Can you try the
attached crude patch for testing caches. You might have to change the
addresses according to your platform. If you could run it, let me know
the results.
best regards,
Aneesh
