The aim of the series is to implement carveout memory management as
discussed during OpenAMP weekly call and defined in proposed document [1]

This first series focus only on adding support of the different types of
carveout memories (dynamic, fixed, platform driver depend...).
64bit resource table will be addressed in a next series.

Changes since V1:
- Minor corrections on first 7 patches (error management)
- Add "memory device" support on the top of first 7 patches.
  Goal is to answer use case reported during OpenAMP weekly discussion:
  - "Be able to specify memory region for vring and buffer allocation, even
    if no specific request defined in firmware resource table."
  Patches offer the capability to create a "memory device" associated to a
  carveout with a dedicated DMA memory pool. Different resource handlers are
  modified to look-up for specific carveout by name. If match found and associated
  "memory device" present, device is used instead of rproc platform device for
  allocation.

Loic Pallardy (16):
  remoteproc: add rproc_va_to_pa function
  remoteproc: add release ops in rproc_mem_entry struct
  remoteproc: introduce rproc_add_carveout function
  remoteproc: introduce rproc_find_carveout_by_da
  remoteproc: modify rproc_handle_carveout to support preallocated
    region
  remoteproc: modify vring allocation to support preallocated region
  remoteproc: st: add reserved memory support
  remoteproc: add name in rproc_mem_entry struct
  remoteproc: add memory device management support
  remoteproc: add memory device registering in rproc_add_carveout
  remoteproc: introduce rproc_find_carveout_by_name function
  remoteproc: look-up memory-device for vring allocation
  remoteproc: look-up memory-device for virtio device allocation
  remoteproc: look-up pre-registered carveout by name for carveout
    allocation
  remoteproc: st: associate memory device to memory regions
  rpmsg: virtio: allocate buffer from parent
