Everyone:

This patchset is the result of my work on adding support for detecting
and reporting reset reason as can be obtained from System Reset
Controller (to be more precise via SRSR register) on i.MX family of
SoC.

Currently list of supported SoC is as follows:

	  - i.MX6 (tested on i.MX6Q)
	  - i.MX7 (tested on i.MX7D)
	  - VFxxx (tested on VF610)

Feedback is wellcome!

Thanks,
Andrey Smirnov
