Because new images place the bootblock in a separate region from the
primary CBFS, performing an update-fit operation requires reading an
additional section and choosing a different destination for the write
based on the image type. Since other actions are not affected by these
requirements, the logic for the optional read and all writing is
implemented in the cbfs_update_fit() function itself, rather than
relying on the main() function for writing as the other actions do.

As per discussion with lawyers[tm], it's not a good idea to
shorten the license header too much - not for legal reasons
but because there are tools that look for them, and giving
them a standard pattern simplifies things.
However, we got confirmation that we don't have to update
every file ever added to coreboot whenever the FSF gets a
new lease, but can drop the address instead.
util/kconfig is excluded because that's imported code that
we may want to synchronize every now and then.

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.

The fmd compiler now processes "(CBFS)" annotations, distilling them
into a comma-separated list of the names of sections containing
CBFSes. This list is the only thing printed to standard output to
enable easy capture and machine consumption by other tools.
Additionally, the ability to generate a tiny header with a define for
the primary CBFS's size is implemented and can be requested via a
new command-line switch.
Here's an example of how to use the new features:
$ ./fmaptool -h layout.h layout_arm_8192.fmd layout.fmap 2>/dev/null
FW_MAIN_A,FW_MAIN_B,COREBOOT
The hypothetical fmd file contains three sections annotated as (CBFS),
the names of which are printed to standard output. As before, a binary
FMAP file named layout.fmap is created; however, because the command
was invoked with -h, a header #define ing the offset of its FMAP
section (i.e. where it will be relative to the base of flash once the
boot image is assembled) is also generated.
BUG=chromium:470407
TEST=Verify that fmd files without a "COREBOOT" section or with one
that isn't annotated as "(CBFS)" are not accepted. Ensure that the
list of CBFS sections matches the descriptor file's annotations and
is led by the "COREBOOT" section. Invoke with the header generation
switch and check that output file for reasonableness.

The buffer API that cbfstool uses to read and write files only directly supports
one-shot operations on whole files. This adds an intermediate partitioned_file
module that sits on top of the buffer system and has an awareness of FMAP
entries. It provides an easy way to get a buffer for an individual region of a
larger image file based on FMAP section name, as well as incrementally write
those smaller buffers back to the backing file at the appropriate offset. The
module has two distinct modes of operation:
- For new images whose layout is described exclusively by an FMAP section, all
the aforementioned functionality will be available.
- For images in the current format, where the CBFS master header serves as the
root of knowledge of the image's size and layout, the module falls back to a
legacy operation mode, where it only allows manipulation of the entire image
as one unit, but exposes this support through the same interface by mapping
the region named SECTION_NAME_PRIMARY_CBFS ("COREBOOT") to the whole file.
The tool is presently only ported onto the new module running in legacy mode:
higher-level support for true "partitioned" images will be forthcoming. However,
as part of this change, the crusty cbfs_image_from_file() and
cbfs_image_write_file() abstractions are removed and replaced with a single
cbfs_image function, cbfs_image_from_buffer(), as well as centralized image
reading/writing directly in cbfstool's main() function. This reduces the
boilerplate required to implement each new action, makes the create action much
more similar to the others, and will make implementing additional actions and
adding in support for the new format much easier.

Previously, this function allowed one to pass a size of 0 in order to
indicate that the entire buffer should be copied. However, the
semantics of calling it this way were non-obvious: The desired
behavior was clear when the offset was also 0, but what was the
expected outcome when the offset was nonzero, since carrying over the
original size in this case would be an error? In fact, it turns out
that it always ignored the provided offset when the size was zero.
This commit eliminates all special handling of 0; thus, the resulting
buffer is exactly as large as requested, even if it's degenerate.
Since the only consumer that actually called the function with a size
of 0 was buffer_clone(), no other files required changes.

This fixes an inconsistency between `cbfstool create` and `cbfstool add` that
was resulting in confusing claims about the amount of free space at the end of a
CBFS. Calls to `cbfstool add` check whether a file fits under a given empty file
entry by testing whether it would collide with the beginning of the *subsequent*
file header; thus, if a file's end is unaligned, its reported size will not
match the actual available capacity. Although deleted entries always end on an
alignment boundary because `cbfstool remove` expands them to fill the available
space, `cbfstool create` doesn't necessarily size a new entries region to result
in an empty entry with an aligned end.
This problem never resulted in clobbering important data because cbfstool would
blindly reserve 64B (or the selected alignment) of free space immediately after
the all-inclusive empty file entry. This change alters the way this reservation
is reported: only the overhang past the alignment is used as hidden padding, and
the empty entry's capacity is always reported such that it ends at an aligned
address.
Much of the time that went into this patch was spent building trust in the
trickery cbfstool employs to avoid explicitly tracking the image's total
capacity for entries, so below are two proofs of correctness to save others time
and discourage inadvertent breakage:
OBSERVATION (A): A check in cbfs_image_create() guarantees that an aligned CBFS
empty file header is small enough that it won't cross another aligned address.
OBSERVATION (B): In cbfs_image_create(), the initial empty entry is sized such
that its contents end on an aligned address.
THM. 1: Placing a new file within an empty entry located below an existing file
entry will never leave an aligned flash address containing neither the beginning
of a file header nor part of a file.
We can prove this by contradiction: assume a newly-added file neither fills to
the end of the preexisting empty entry nor leaves room for another aligned
empty header after it. Then the first aligned address after the end of the
newly-inserted file...
- CASE 1: ...already contains a preexisting file entry header.
+ Then that address contains a file header.
- CASE 2: ...does not already house a file entry header.
+ Then because CBFS content doesn't fall outside headers, the area between
there and the *next* aligned address after that is unused.
+ By (A), we can fit a file header without clobbering anything.
+ Then that address now contains a file header.
THM. 2: Placing a new file in an empty entry at the very end of the image such
that it fits, but leaves no room for a final header, is guaranteed not to change
the total amount of space for entries, even if that new file is later removed
from the CBFS.
Again, we use contradiction: assume that creating such a file causes a
permanent...
- CASE 1: ...increase in the amount of available space.
+ Then the combination of the inserted file, its header, and any padding
must have exceeded the empty entry in size enough for it to cross at
least one additional aligned address, since aligned addresses are how
the limit on an entry's capacity is determined.
+ But adding the file couldn't have caused us to write past any further
aligned addresses because they are the boundary's used when verifying
that sufficient capacity exists; furthermore, by (B), no entry can ever
terminate beyond where the initial empty entry did when the CBFS was
first created.
+ Then the creation of the file did not result in a space increase.
- CASE 2: ...decrease in the amount of available space.
+ Then the end of the new file entry crosses at least one fewer aligned
address than did the empty file entry.
+ Then by (A), there is room to place a new file entry that describes the
remaining available space at the first available aligned address.
+ Then there is now a new record showing the same amount of available space.
+ Then the creation of the file did not result in a space decrease.

Currently `xcompile` generates `.xcompile` with the following at the
top.
# platform agnostic and host tools
IASL:=iasl
HOSTCC:=gcc
The assignment `:=` doesn’t allow to override the variable. So use `?=`
instead so the host compiler can be passed to coreboot.
HOSTCC=gcc-5 make
Note, that this is just a hack, as the existence of `gcc` is checked
beforehand.

If the buildgcc is interrupt by Ctrl-C, probably part of
an archive is downloaded. If we run buildgcc again, the
incomplete archive would be considered as cached file
and skipped.
We check file hashes to see if the file is complete. If test
is failed, we need to delete the partially-downloaded file
and download it again.
sha1sum is quite different among the distributions.
Only Linux, Cygwin, Darwin have been tested.
Once new archive is deployed, a new checksum would be created,
which should be uploaded along with the script buildgcc.
