The region infrastructure provides a means of abstracting
access to different types of storage such as SPI flash, MMC,
or just plain memory. The regions are represented by
region devices which can be chained together forming subregions
of the larger region. This allows the call sites to be agnostic
about the implementations behind the regions. Additionally, this
prepares for a cleaner API for CBFS accesses.

The cbfstool handling of new-style FMAP-driven "partitioned" images
originally disallowed the use of x86-style top-aligned addresses with
the add.* and layout actions because it wasn't obvious how they should
work, especially since the normal addressing is done relative to each
individual region for these types of images. Not surprisingly,
however, the x86 portions of the build system make copious use of
top-aligned addresses, so this allows their use with new images and
specifies their behavior as being relative to the *image* end---not
the region end---just as it is for legacy images.

These new-style firmware images use the FMAP of the root of knowledge
about their layout, which allows them to have sections containing raw
data whose offset and size can easily be determined at runtime or when
modifying or flashing the image. Furthermore, they can even have
multiple CBFSes, each of which occupies a different FMAP region. It is
assumed that the first entry of each CBFS, including the primary one,
will be located right at the start of its region. This means that the
bootblock needs to be moved into its own FMAP region, but makes the
CBFS master header obsolete because, with the exception of the version
and alignment, all its fields are redundant once its CBFS has an entry
in the FMAP. The version code will be addressed in a future commit
before the new format comes into use, while the alignment will just be
defined to 64 bytes in both cbfstool and coreboot itself, since
there's almost no reason to ever change it in practice. The version
code field and all necessary coreboot changes will come separately.
