[Elinux-wiki-dev] Text for "core_freq" parameter in Raspberry Pi config.txt

This notes that the L2 cache is shared and that changing the core frequency
would impact the ARM CPU performance.
However, I believe that the Pi 2 CPU has its own, separate, L2 cache.
I dropped the "core_freq" setting as low as possible (80Mhz) and found no
measurable drop in CPU performance (for my headless setup).

Perhaps the wording could be changed to say that this is a problem for the
earlier ARMv6 Pi 1 (B, B+ etc) only.
