There are various functions which announce that booting is imminent and
do related preparation. Most of these are arch-specific.
In practice, most archs do the a similar thing. It would be better to
change "the a" to "a"
have a common function, with perhaps some events for things that are
really arch- and board-specific.
Create a new function for this. For now, nothing uses it. Be careful to
avoid using BIT() macros which are not available with host tools.
