Subject: [RFT 0/2] RISC-V: handle missing "no-map" properties for OpenSBI's PMP protected regions

Hey folks,

I was kinda sitting around hoping that someone who cared about
hibernation would decide to go and work on some patches that permitted
using it without having to use NONPORTABLE, but that has not yet
happened so here I am.

I've marked this RFT as I have not got a setup to test hibernation on a
system that suffers from the OpenSBI issue, nor have I used crash
kernels at all.

Thanks,
Conor.
