This gets things that are needed early in the boot, like what type of monitor
is connected to the system so the early kernel startup messages will go to
the correct place, etc. This is not to be exported to the user. It is only
used for kernel startup before the storage driver comes becomes ready, or
if the system is configured without the storage driver. Once the storage
driver is up, this info can be read and written as a normal block device
from flash memory.
