V13:
Add R-b tag from Rob for patch 1.
Drop the reserved memory node from patch 2 per Rob's comment.
Mathieu, Bjorn
Only patch 2 not have R-b/A-b tag, but since Rob's only has a minor comment, and
addressed in this version, is it ok for you take into remoteproc next branch?
Thanks.
V12:
Add maxItems to avoid dt_bindings_check fail
Rebased on top of linux-next
V11:
Per Rob's comments, fix memory-region in patch 1/10
Rebased on top of Linux-next
V10:
Per Rob's comments, fix patch 1/10
V9:
Per Mathieu's comments,
update the tile of yaml in patch 2/10
update the Kconfig and MODULE_DESCRIPTION, I merge this change in patch 8/10,
since this is a minor change, I still keep Mathieu's R-b tag. If any objection, I could remove.
Add R-b tag in Patch 10/10
Rob, please help review patch 1/10 and 2/10
V8:
Address sparse warning in patch 4/10 reported by kernel test robot
V7:
Add R-b tag from Mathieu
vdevbuffer->vdev0buffer in patch 1/10, 7/10
correct err msg and shutdown seq per Mathieu's comments in patch 10/10
Hope this version is ok to be merged.
V6:
Add R-b tag from Mathieu
Convert imx-rproc.txt to yaml and add dt-bindings support for i.MX8MQ/M, patch 1/10 2/10
No other changes.
V5:
Apply on Linux next
Add V5 subject prefix
Add R-b tag from Bjorn for 1/8, 2/8, 3/8
https://patchwork.kernel.org/project/linux-remoteproc/cover/20201229033019.25899-1-peng.fan@nxp.com/
V4:
According to Bjorn's comments, add is_iomem for da to va usage
1/8, 2/8 is new patch
3/8, follow Bjorn's comments to correct/update the err msg.
6/8, new patch
8/8, use dev_err_probe to simplify code, use queue_work instead schedule_delayed_work
V3:
Since I was quite busy in the past days, V3 is late
Rebased on Linux-next
Add R-b tags
1/7: Add R-b tag of Mathieu, add comments
4/7: Typo fix
5/7: Add R-b tag of Mathieu, drop index Per Mathieu's comments
6/7: Add R-b tag of Mathieu
7/7: Add comment for vqid << 16, drop unneeded timeout settings of mailbox
Use queue_work instead of schedule_delayed_work
free mbox channels when remove
https://lkml.org/lkml/2020/12/4/82
V2:
Rebased on linux-next
Dropped early boot feature to make patchset simple.
Drop rsc-da
https://patchwork.kernel.org/project/linux-remoteproc/cover/20200927064131.24101-1-peng.fan@nxp.com/
V1:
https://patchwork.kernel.org/cover/11682461/
This patchset is to support i.MX8MQ/M coproc.
The early boot feature was dropped to make the patchset small in V2.
Since i.MX specific TCM memory requirement, add elf platform hook.
Several patches have got reviewed by Oleksij and Mathieu in v1.

could take the memory as normal memory or io mapped memory.

It is using devm_ioremap, so not devm_ioremap_resource. Correct
the error message and print out sa/size.

We might need to map an region multiple times, becaue the region might
be shared between remote processors, such i.MX8QM with dual M4 cores.
So use devm_ioremap, not devm_ioremap_resource.
