Cover letter [PATCH 0/7] arm-smmu: Implementation and context format differentiation
Hi all,
This is almost 3 separate sub-series, but there's enough interdependency and horrid merge conflicts that I've been keeping it all together.
- Patches 1-3 rationalise implementation-specific details and errata, in order to start shovelling in yet more wonderful workarounds.
- Patches 3-6 do a broadly similar thing for context formats, breaking the effective hard-coding to allow it to become a runtime choice. (With the bonus of unblocking short-descriptor support, once I find and revive the hac^Wpatches I was using for that.)
- Patch 7 then takes advantage of the previous changes to support the hilarious raison d'etre of MMU-401, in all its glory.
This is all based on top of the ThunderX patches in Will's iommu/devel branch. It also conflicts somewhat with my per-domain page size series; since this is probably less contentious, I expect I'll optimistically rebase that on top of this one before I post it again.
Robin.
