Hello all,

I've created a more convenient PDF document of my proposal to give our
enhanced PMP four security levels, available here:
http://www.jhauser.us/RISCV/Hauser_enhancedPMP-0.2.pdf

The purpose is to provide additional options for better protection than
MML = 0, for those times when it is not yet possible to set MML = 1.
More rationale is in the document.

Regards,
