Hi, Actually, what I mean is, there are two independent L1 caches (one in first e500 core and other in second e500 core) in mpc8572. Now, if I am running cache test(POST) on mpc8572, I must somehow make sure that it tests both the L1 caches. Generally, earlier there used to be one e500 core, one L1 cache and hence cache test does not need to query whether it is testing L1 of first core or L1 of second.
So, how to make sure that I am testing L1 caches on _both_ the e500 cores?
