* wil6210: support for platform specific crash recoveryLior David2016-01-07
| | | | | | | | | | | | | | | | | Added a simple interface for platform to perform crash recovery. When firmware crashes, wil driver can notify the platform which can trigger a crash recovery process. During the process the platform can request a ram dump from the wil driver as well as control when firmware recovery will start. This interface allows the platform to implement a more advanced crash recovery, for example to reset dependent subsystems in proper order, or to provide its own notifications during the recovery process.

* wil6210: dump firmware memory when firmware crashesVladimir Kondratiev2015-10-09
When firmware crashes, just before firmware recovery, dump the firmware memory to a devcoredump device. The resulting dump can be read from user space to be used in offline crash analysis.
