Subject[PATCH v2 00/16] remoteproc: add fixed memory region support
Date
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
