I think sgx has no iommu on the SoC, it just the sgx internal mmu, so
those changes should not be needed.

Anyways, the branches should not be rebased as that makes it a moving
target for anybody trying to develop against them. It's better to
set up a new branch for something that needs rebasing.

So could you please update your scripts to start building kernel
version based branches for example?

I suggest we have pvr-v5.4 branch and pvr-v5.5 branch, then pvr-v5.6
branch after -rc1 and so on. For most part I can see the old branches
just get forgotten, but I can see folks wanting to backport
some patches to the pvr-v5.4 branch as that a lts kernel.

If you want to keep merging things together into some master branch,
then that can be done after building a temporary new branch, and
doing git merge -s ours. That way the old branch need no rebasing ;)
