Ronald G. Minnich ed4aa043c6 cbfstool: add ppc64 support
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.

Herman Hollerith would be proud.

Patrick Georgi 8a3592eec3 build system: Switch to fmap based firmware layout
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

Patrick Georgi 9731119b32 cbfstool: make top-aligned address work per-region
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.

This patch fixes compilation of cbfstool on Cygwin.

As reported in http://review.coreboot.org/#/c/10027
cbfstool on Cygwin likes to be compiled with -D_GNU_SOURCE.
That patch was abandoned because it would unwantedly turn on
more GNU extensions. Instead of doing that, only enable the
define on Cygwin, switch to -std=gnu99 instead of -std=c99 to
make fileno and strdup actually available.
A MINGW32 check that was forgotten in Makefile was copied over
from Makefile.inc to keep the two files in sync.

This patch has no impact on non-Windows builds.

So it is “deteled” as the type changed. But the name was not changed to
match the *(empty)* heuristic.

So also adapt the name when removing a file by writing a null byte to
the beginning of the name, so that the heuristic works. (Though remove
doesn't really clear contents.)

Patrick Georgi 89f20340d5 cbfstool: Add support for hashes as file metadata
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.

for the utilities to provide a printk() declaration within

Patrick Georgi b946f12ed0 cbfstool: make fmap search more strict
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).

Patrick Georgi 59e52b975e cbfstool: add new add-master-header command
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.

removed when cbfs_locate is removed as cbfs_add has no smarts
