Hi all,
there are a bunch of IOMMU APIs that are entirely unused, or only used as
a private communication channel between the FSL PAMU driver and it's only
consumer, the qbman portal driver.
So this series drops a huge chunk of entirely unused FSL PAMU
functionality, then drops all kinds of unused IOMMU APIs, and then
replaces what is left of the iommu_attrs with properly typed, smaller
and easier to use specific APIs.
Changes since v2:
- remove a comment fragment a little bit earlier
- fix the aperture end passed to pamu_config_ppaace
- fix a few trivial typos
- remove more unused arguments to pamu_config_ppaace
- do not accidentally enable lazy flushing for non-dma domains
Changes since v1:
- use a different way to control strict flushing behavior (from Robin)
- remove the iommu_cmd_line wrappers
- simplify the pagetbl quirks a little more
- slightly improved patch ordering
- better changelogs
