Cover letter [PATCH 0/7] Make PMP encoding usable for non-hart PMPs
The Tenstorrent RISC-V IOMMU implements PMPs with MMRs in the same format as specified in the RISC-V ISA for the hart CSRs. This series splits out the PMP encoding functions so it can be shared by both users.
I moved this series out of the Tenstorrent Atlantis platform series that included IOMMU support, tried to do better at splitting it up, tidied and improved code.
The new user of the API can be seen here for reference (will not quite compile with this new series):
https://lore.kernel.org/opensbi/[email protected]/
I will post that one out again after the base Atlantis platform and this series is merged.
Thanks,
Nick
