V8:
Rebased on linux-next/master tag: next-20220927
V7:
Per comments from Arnaud Pouliquen:
Typo fixes
Added A-b tag
V6:
Rename rproc_firmware_recovery to rproc_boot_recovery
Drop the unlock/lock when do reproc_attach_recovery
V5:
Rename RPROC_FEAT_ATTACH_RECOVERY to RPROC_FEAT_ATTACH_ON_RECOVERY
Add kerneldoc for rproc features
Change rproc_set_feature to return int type and add a max feature check
Use __rproc_detach and __rproc_attach when do attach recovery
https://patchwork.kernel.org/project/linux-remoteproc/cover/20220615032048.465486-1-peng.fan@oss.nxp.com/
V4:
Based on Bjorn's comments on V2-2
Move the rproc_has_feature/rproc_set_feature to remoteproc_internal.h and
Keep rproc_features still in remoteproc.h, because we use
RPROC_MAX_FEATURES to declare bitmap.
Update commit log for patch 2/2, and add comments
https://patchwork.kernel.org/project/linux-remoteproc/cover/20220323034405.976643-1-peng.fan@oss.nxp.com/
V3:
Resend the wrong labeled patchset
https://patchwork.kernel.org/project/linux-remoteproc/list/?series=621311
Write a cover-letter
To i.MX8QM/QXP, they have a M4 core self-recovery capability without
Linux loading firmware. The self recovery is done by
SCU(System Control Unit). Current remoteproc framework only support Linux
help recovery remote processor(stop, loading firmware, start). This
patchset is support remote processor self recovery(attach recovery).
In order to avoid introducing a new variable(bool support_self_recovery),
patch 1 introduce a new function, rproc_has_feature to make code easy to
extend, cleaner, such as we could move "bool has_iommu" to
rproc_has_feature(rproc, RPROC_FEAT_IOMMU).
Patch 2 is introduce a new function rproc_attach_recovery for
self recovery, the original logic move to rproc_firmware_recovery meaning
needs linux to help recovery.
V2-version 2:
https://patchwork.kernel.org/project/linux-remoteproc/list/?series=621311
Introduce rproc_has_feature
V2-version 1:
https://patchwork.kernel.org/project/linux-remoteproc/patch/20220126085120.3397450-1-peng.fan@oss.nxp.com/
Nothing change in V2.
Only move this patch out from
https://patchwork.kernel.org/project/linux-remoteproc/list/?series=604364

remote processor may support:
- boot recovery with help from main processor
- self recovery without help from main processor
- iommu
- etc
Introduce rproc features could simplify code to avoid adding more bool
flags

Current logic only support main processor to stop/start the remote
processor after crash. However to SoC, such as i.MX8QM/QXP, the
remote processor could do attach recovery after crash and trigger watchdog
to reboot itself. It does not need main processor to load image, or
stop/start remote processor.
Introduce two functions: rproc_attach_recovery, rproc_boot_recovery
for the two cases. Boot recovery is as before, let main processor to
help recovery, while attach recovery is to recover itself without help.
To attach recovery, we only do detach and attach.

Hi Peng,
Thanks for your patch.
Tags are useful, but more accurate method is to use --base option of git
format-patch.
This can inform others what base-commit was used. It is also useful when
you have prerequisite patches.
Hope this helps.
Thanks,
Tanmay

Yes, I see. linux-next/master would force update every day, so I am not
sure base-commit would work for linux-next/master branch.
