>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 adds a configurable option to move the recovery/coredump interfaces to sysfs. If the feature flag is selected it would move these interfaces to sysfs and remove the equivalent debugfs interface. '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: 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.
