This patch series moves the coredump functionality to a separate file and adds "inline" coredump feature. Inline coredump directly copies segments from device memory during coredump to userspace. This avoids extra memory usage at the cost of speed. Recovery is stalled until all data is read by userspace. Changelog: v4 -> v3: - Write a helper function to copy segment memory for every dump format - Change segment dump fn to add offset and size adn covert mss driver v3 -> v2: - Move entire coredump functionality to remoteproc_coredump.c - Modify rproc_coredump to perform dump according to conf. set by userspace - Move the userspace configuration to debugfs from sysfs. - Keep the default coredump implementation as is v2 -> v1: - Introduce new file for coredump. - Add userspace sysfs configuration for dump type.
