2017-02-07hw/misc: New "unimplemented" sysbus devicePeter Maydell
Create a new "unimplemented" sysbus device, which simply accepts all read and write accesses, and implements them as read-as-zero, write-ignored, with logging of the access as LOG_UNIMP. This is useful for stubbing out bits of an SoC or board model which haven't been written yet.
