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.

[mszyprow: rebased onto v3.18-rc1, added error messages when property value
is missing]
Why? What if the boot loader has already set these up appropriately? Why
should we force people to list these in the DT?
The error message is displayed only when user provided prefetch related
properties without any value (empty properties). Something that Mark Rutland
requested here: https://lkml.org/lkml/2014/9/24/426 I'm sorry if I didn't
describe it clearly enough.
Best regards
