From: Peng Fan <peng.fan@xxxxxxx> 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 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@xxxxxxxxxxx/ Nothing change in V2.
