Coredump Device
Overview
The coredump device is a pseudo-device driver with two types.A COREDUMP_TYPE_MEMCPY type exposes device tree bindings for memory address/size values to be included in any dump. And the driver exposes an API to add/remove dump memory regions at runtime. A COREDUMP_TYPE_CALLBACK device requires exactly one entry in the memory-regions array with a size of 0 and a desired size. The driver will statically allocate memory of the desired size and provide an API to register a callback function to fill that memory when a dump occurs.
