Hi Aneesh,
I've enabled the L2 cache for Trats board. Please find results from performance tests. The test function as well as my way for enabling L2 are attached to this e-mail.

Have you had similar results with OMAP? Do you do more configuration when enabling the L2 at OMAP?
At least on some parts, it's similar here. The normal sequence of operations is loading a relatively small payload (kernel, maybe device tree) from storage and then booting it (which turns off L2 anyways). This is why I was willing to disable DCACHE as a USB workaround, the common use-case doesn't see a great deal of help from dcache being on.
I saw some pretty significant perf. boost with L1, I was planning to check L2 on mx6q, but I'm not sure if it's worth it anymore.
Best regards, Marek Vasut
I can agree, that enabling L1 provides significant performance boost. In our case, enabling L2 gives very little boost. Please try L2 on mx and share the results.
