[Xen-devel] [PATCH v3 0/6] xen/arm: Add support for mapping mmio-sram nodes into dom0

From: "Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxxx>

This series adds support for mapping mmio-sram nodes into dom0
as normal uncached MEMORY with RWX perms.

If the no-memory-wc prop is present in the DTB node, we create
DEVICE RW mappings instead.

Julien, I've scratched the map_regions_mattr name since we are now
passing p2m_type_t's instead. I borrowed the short p2mt name from
existing code.

Comments welcome!

Best regards,


v2 -> v3:
* Drop RFC
* Add comment on outer-shareable choice for non-cached mem
* Spellfix existance -> existence
* Add comment on props usage
* Props matching now only supports a single property
* Dropped p2m_access in plumbing for mapping attributes
* Rename un/map_regions to un/map_regions_p2mt
* Add path to mmio-sram device-tree bindings docs in commit msg
* Add a comment on inheriting parent mem attributes
* Dropped the mmio-sram bus

v1 -> v2
* Replace the .map method with a list of match -> map attributes
* Handle no-memory-wc by mapping as DEVICE RW
* Generalize map_regions_rw_cache instead of adding new functions
