Subject: [PATCH v4 0/7] xen/arm: Add support for mapping mmio-sram nodes into dom0
Date: Fri, 23 Sep 2016 20:53:15 +0200 [thread overview]
Message-ID: <1474656802-24081-1-git-send-email-edgar.iglesias@gmail.com> (raw)
From: "Edgar E. Iglesias" <edgar.iglesias@xilinx.com>
This series adds support for mapping mmio-sram nodes into dom0
as normal uncached MEMORY with RW perms.
If the no-memory-wc prop is present in the DTB node, we create
DEVICE RW mappings instead.
Comments welcome!
Best regards,
Edgar
ChangeLog:
v3 -> v4:
* Rename p2m_mmio_direct_nc -> p2m_mmio_direct_dev
* Rename p2m_mem_nc p2m_mmio_direct_nc
* Make p2m_mmio_direct_nc non-executable to match p2m_mmio_direct_c
* Fix typos in comments regarding shareability
* Add reference to ARMv8 specs for outer sharability attr
* Add comment describing map_regions_p2mt
* Mention the p2m type inheritance in the commit msg of path #6
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
