Apologies for ping (I hate doing that), but I haven't heard anything
from you.  Do you want me to re-submit this set, or are you willing to
take this and apply the relevant Acks?

> 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.
> 
> v4 => v5:
>  - Check for invalid 'count' (command read length) in write fn()s
>   
> 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
>  - Populate MAINTAINERS
>  - 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
>
