- People sometimes have their editor auto-add themselves to files even

- Or they let the editor automatically update the copyright year,
because why not?
- Who is the copyright holder "The coreboot project Authors"?

Sidestep all these issues by simply not putting these notices in

Implement postcar stage cbmem console support. The postcar stage
is more like ramstage in that RAM is already up. Therefore, in
order to make the cbmem console reinit flow work one needs the cbmem
init hook infrastructure in place and the cbmem recovery called.
This call is added to x86/postcar.c to achieve that. Additionally,
one needs to provide postcar stage cbmem init hook callbacks for
the cbmem console library to use. A few other places need to
become postcar stage aware so that the code paths are taken.
Lastly, since postcar is backed by ram indicate that to the
cbmem backing store.

The current CBMEM code contains an optimization that maintains the
structure with information about the CBMEM backing store in a global
variable, so that we don't have to recover it from cbmem_top() again
every single time we access CBMEM. However, due to the problems with
using globals in x86 romstage, this optimization has only been enabled
in ramstage.
However, all non-x86 platforms are SRAM-based (at least for now) and
can use globals perfectly fine in earlier stages. Therefore, this patch
extends the optimization on those platforms to all stages. This also
allows us to remove the requirement that cbmem_top() needs to return
NULL before its backing store has been initialized from those boards,
since the CBMEM code can now keep track of whether it has been
initialized by itself.
