driver: Google Memory Console
This patch introduces the 'memconsole' driver. Our firmware gives us access to an in-memory log of the firmware's output. This gives us visibility in a data-center of headless machines as to what the firmware is doing. The memory console is found by the driver by finding a header block in the EBDA. The buffer is then copied out, and is exported to userland in the file /sys/firmware/log.
