Suman Anna	faeadbb640	remoteproc: Check for NULL firmwares in sysfs interface ... The remoteproc framework provides a sysfs file 'firmware' for modifying the firmware image name from userspace. Add an additional check to ensure NULL firmwares are errored out right away, rather than getting a delayed error while requesting a firmware during the start of a remoteproc later on.

Sarangdhar Joshi	608d792192	remoteproc: Add RPROC_DELETED state ... Add new state RPROC_DELETED to handle synchronization between rproc_del() and other operations on rproc. This state represents the rproc device that has been "deleted".

Matt Redfearn	2aefbef041	remoteproc: Add a sysfs interface for firmware and state ... This patch adds a sysfs interface to rproc allowing the firmware name and processor state to be changed dynamically. State was previously available in debugfs, and is replicated here. The firmware file allows retrieval of the running firmware name, and a new one to be specified at run time, so long as the remote processor has been stopped.
