[PATCH v4 0/6] remoteproc: Add driver for STMicroelectronics platforms

ST's platforms often have multiple co-processors (usually ST40s or ST231s)
on-board.  This provides the Linux-side infrastructure to flash and boot
them successfully.

This set has been tested on an STiH410-B2120.

v3 => v4:
 Suggested-by: Suman Anna <s-anna at ti.com>
 - Move to using 'reserved-memory' API
   - New 'reserved-memory' nodes
   - Remove memory locations from RemoteProc's DT node's reg properties
   - Remove C code obtaining/allocating DMA memory
 - Re-order .start() and .stop() ops
 - Add protection around Reset API in error path
 - Explicitly set .has_iommu to false

v2 => v3:
 - Generify syscon property (st,syscfg-boot => st,syscfg)
 - Rename IP in DT bindings doc (Remote Processor => Co-Processor)
 - Remove superfluous 'clock-names' property
 - Remove superfluous 'reg-names' property
 - Clean-up DTS formatting
 - Use strings in debugfs to control procs ('1|0' => 'start|stop')
 - Align copyright statement with MODULE() macros
 - Rename driver data structure ('st_rproc' => 'ddata')
 - Addition of a full error path in .start()

v1 => v2:
 - Remove Linux implementation specific comment from binding document
 - Force debugfs '0' to shutdown co-processor - rather than !1
 - Supply more detailed commit message
 - Propagate errors back from .stop()
 - Review GPL wording
 - Supply original author's SoBs
