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.

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.

Currently, compression is only allowed at subheader level (e.g. cbfs_stage,
cbfs_payload_segment). This change adds compression field to each file's
header so that any cbfs file can be compressed.
With the necessary additions in coreboot and libpayload, the following sample
code can load a compressed file:
const char *name = "foo.bmp";
struct cbfs_file *file = cbfs_get_file(media, name);
void *dst = malloc(ntohl(file->uncompressed_size));
dst = cbfs_get_file_content(media, name, type, file, dst);
cbfs_stage and cbfs_payload_segment continue to support compression at
subheader level because stages and payloads have to be decompressed to the load
address, which is stored in the subheader. For these, file level compression
should be turned off.
