[PATCH v2 0/3] remoteproc: complete fixed memory region support

[Loic Pallardy]

This new series corresponds to the remaining patches from [1]
addressing fixed memory region support for remote processor.

The three remaining patches allow to:
- assign a specific memory region to vdev sub device. As all virtio based
  services are using virtio device parent for memory allocation, I propose to
  keep a dedicated vdev device per virtio link for memory allocation. A second
  step will be to used virtio device itself.
- migrate ST driver on new memory carveout management
- allocate virtio rpmsg buffer from parent device

Regards,
Loic
