> Firmware on certain boards (e.g. ODROID-U3) can leave incorrect L2C prefetch
> settings configured in registers leading to crashes if L2C is enabled
> without overriding them. This patch introduces bindings to enable
> prefetch settings to be specified from DT and necessary support in the
> driver.
