I think that is an interesting idea but I would expect some push back
from OS loader maintainers. I would expect they don't want to be
constrained by the lowest common capabilities of the platforms they
still support/run on in the ecosystem. Not to mention the challenges
around servicing and/
During CpuDxe initialization, MMU will be setup with the highest
mode that HW supports.

There is no point to set satp to bare mode as that should be the
default mode when booting edk2.

Normally, DXE driver would add device resource to GCD before start using.
But some key resources such as uart used for printing info at very early
stage.
Those resources should be populated to HOB in SEC phase so they are
added to GCD before MMU enabled.

This series adds MMU support for RISC-V. Only SV39/48/57 modes
are supported and tested. The MMU is required to support setting
page attribute which is the first basic step to support security
booting on RISC-V.
There are two parts:
1. Add MMU base library. MMU will be enabled during
CpuDxe initia
Add an API to retrieve satp register value.

Add the bit masks for DLL Characteristics, used within the optional
header of a PE, to the PeImage.h header file.

Automatically set the nxcompat flag in the DLL Characteristics field of
the Optional Header of the PE32+ image. For this flag to be set
automatically, it must, the section alignment must be evenly divisible
by 4K (EFI_PAGE_SIZE) and no section must be executable and writable.

Hi Oliver,
I see the PR you linked is marked as draft and test.
I'm happy to help push this if you can confirm when you're done testing.
Thanks,
