/* This file is the basis for the ssdt_mem[] variable in src/acpi.c.
 * It defines the contents of the memory device object.  At
 * runtime, a dynamically generated SSDT will contain one copy of this
 * AML snippet for every possible memory device in the system.  The
 * objects will be placed in the \_SB_ namespace.
 *
 * In addition to the aml code generated from this file, the
 * src/acpi.c file creates a MTFY method with an entry for each memdevice:
 *     Method(MTFY, 2) {
 *         If (LEqual(Arg0, 0x00)) { Notify(MP00, Arg1) }
 *         If (LEqual(Arg0, 0x01)) { Notify(MP01, Arg1) }
 *         ...
 *     }
