> This series improves the PMP detection by detecting the minimum
> granularity and address size supported by the platform. It prevents any pmp
> region writes that are not supported by platform leading to more robust and
> secure implementation.

> Tested generic platform for following boards:
> 1. Qemu
> 2. HiFive Unleashed
> 3. OmniXtend

Make sure you test on QEMU RV32 as well.
