[PATCH v4 0/6] Add virtio-mmio support to m68k virt machine

[Daniel Palmer]

Lets start making the m68k virt machine support useful.

First we need to fix some m68k endian issues.

Then allow virtio mmio driver instances to be created with
platform data and fix a minor endian issue.

Finally, add the code for the board to create the instances.

v4:
  - Small changes to "board: qemu: m68k: Create virtio mmio instances"
    requested by Simon.
  - Add another patch to make the virtio cmd depend on CONFIG_VIRTIO_BLK
    as the build breaks if it isn't selected.

v3:
  - Fix the bug with the vendor string in virtio-blk properly,
    this removes the last endian hack in virtio-mmio
  - Leave the current behaviour for readl() for coldfire as it
    breaks thing.

v2:
  - Added patch to fix readl() etc on m68k, hopefully this
    doesn't break everything. This should match Linux now.
  - Added patch to fix sys reset which is broken by the above
  - Hacks to virtio-mmio are gone because they aren't needed
    anymore, just one minor endian fix now.
  - Removed RFC because it looks good to me*.


* I wouldn't trust me. :)
