>From Android R onwards Google has restricted access to debugfs in user and user-debug builds. This restricts access to most of the features exposed through debugfs. This patch series removes the recovery/coredump entries from debugfs and adds a configurable option to expose these interfaces from sysfs. 'Coredump' and 'Recovery' are critical interfaces that are required for remoteproc to work on Qualcomm Chipsets. Coredump configuration needs to be set to "inline" in debug/test build and "disabled" in production builds. Whereas recovery needs to be "disabled" for debugging purposes and "enabled" on production builds. Changelog: v3 -> v2: - Remove the coredump/recovery entries from debugfs - Expose recovery/coredump from sysfs under a feature flag v1 -> v2: - Correct the contact name in the sysfs documentation. - Remove the redundant write documentation for coredump/recovery sysfs - Add a feature flag to make this interface switch configurable.
