Note -- it's important to understand that there's a difference between oprofile/perf on A9, and oprofile/perf on specific boards. On A9 generically, perf (and hence oprofile -- oprofile is built on perf now) works. However, the way that the performance counter interrupts are routed is dependent on the SoC. OMAP4 and later have an unusual way of doing this, which is why perf doesn't currently work upstream for these platforms.
