The cbfs master header's offset and romsize fields are absolute values
within the boot media proper. Therefore, when adding a master header
provide the offset of the CBFS region one is operating on as well as
the absolute end offset (romsize) to match expectations.
Built with and without CBFS_SIZE != ROM_SIZE on x86 and ARM device. Manually
inspected the master headers within the images to confirm proper caclulations.

typial.
- Add an option -R for the copy source fmap region.
Use: cbfstool copy -r target-region -R source-region.
- Don't generate a CBFS master header because for fmap regions, we
assume that the region starts with a file header.
Use cbfstool add-master-header to add it afterwards, if necessary.
- Don't copy files of type "cbfs master header" (which are what cbfstool
add-master-header creates)
- Leave room for the master header pointer
- Remove -D command line option as it's no longer used.

The constant for ppc64 is 'hotstuff'. For many reasons.
Note that line 2894 of elf.h is not indented. This is because in the
original the line begins with a space. Checkpatch rejects that.
Checkpatch also rejects changing the space to a tab because that makes
it more than 80 chars. I rejected breaking the line because it makes it
even less readable. All the changes forced by checkpatch make the code
less readable.

We still add a master header for compatibility purposes, and the default
layouts don't cover anything non-coreboot (eg. IFD regions) yet.
The default layouts can be overridden by specifying an fmd file, from
which the fmap is generated.
Future work:
- map IFD regions to fmap regions
- non-x86: build minimalistic trampolines that jump into the first cbfs
file, so the bootblock can be part of CBFS instead of reserving a
whole 64K for it.
- teach coreboot's cbfs code to work without the master header
- teach coreboot's cbfs code to work on different fmap regions

The former interpretation sprung from the x86 way of doing things
(assuming top-alignment to 4GB). Extend the mechanism to work with CBFS
regions residing elsewhere.
It's compatible with x86 because the default region there resides at the
old location, so things fall in place. It also makes more complex
layouts and non-x86 layouts work with negative base addresses.

Older gcc versions throws a warning when a struct or union is
declared without a valid name (anonymous). This patch enables the
feature for older gcc versions so that no warning will be issued.

They allow optimizing a verification of a whole CBFS image by only
dealing with the headers (assuming you choose to trust the hash
algorithm(s)).
The format allows for multiple hashes for a single file, and cbfstool
can handle them, but right now it can't generate such headers.
Loosely based on Sol's work in http://review.coreboot.org/#/c/10147/,
but using the compatible file attribute format. vboot is now a hard
dependency of the build process, but we import it into the tree for
quite a while now.

Up to now, if both fmap and a master header existed, the master header
was used. Now, use the master header only if no fmap is found.

On x86, the bootblock can (and will) become part of the regular file
system, so there's no distinct fixed-size region for the bootblock
there.

$(src) is not defined when building directly from the cbfs directory (that is,
when building cbfs as standalone, running make in the cbfs directory), so we
need to define the path to the commonlib include path relative to $(top).

Instead of reaching into src/include and re-writing code
allow for cleaner code sharing within coreboot and its
utilities. The additional thing needed at this point is
for the utilities to provide a printk() declaration within
a <console/console.h> file. That way code which uses printk()
can than be mapped properly to verbosity of utility parameters.

Since fmap doesn't come with a checksum, we resort to a number of
heuristics to determine if a given location hosts an fmap (instead of
another data structure that happens to store the fmap magic string at
the right location).
The version test is particularly effective against strings containing
the magic (which either terminate with 0, or have some other ASCII data,
but rarely a '\001' byte inside the string).

The command adds a new cbfs file, fills in the CBFS meta data in cbfs
master header format, then points the master header pointer (which
resides at the last 4 bytes of the CBFS region) to the data area of the
new file.
This can leak some space in CBFS if an old-style CBFS with native master
header gets the treatment, because a new header is created and pointed
at. flashmap based images have no such header, and the attempt to create
a second file with the (hardcoded) name will fail.
