ERRMEM
======
This binding defines the error memory region. The error memory is a driver
that allows the persistent storage of data which is mostly meant to
be for a post mortem analysis, arbitrary other fault or system analysis
or for documentation of critical or defective system states.

Required properties:
- compatible : "adit,errmem".
- reg : base address and size of the errmem region.
		base address of errmem should not overlap
		with linux,usable-memory.

Example:

	errmem: errmem {
		compatible = "adit,errmem";
		reg = <0x00000000 0x53f00000 0x0 0x100000>;
	};
