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


Peng Fan (2):
  remoteproc: introduce rproc features
  remoteproc: support attach recovery after rproc crash
