Patrick Georgi aa44dbd364 cbfstool: move tests for fixed-location files earlier
... and the assert is gone.
The actual action of adding a just-right file can be moved after the tests
since it's exactly the condition those tests don't continue or break on.

Patrick Georgi db01ddfd49 cbfstool: prepare moving tests earlier
The assert() makes sure the if() holds true. But that assert won't survive for
long.

We will want to create headers that live outside the final image at some point

So far it's still unused, but its purpose will change:
It will become an offset to another structure that contains additional file
attributes.

This change is compatible because the binary format doesn't change and so far
the field was always set to 0, which can serve nicely as 'unused' field.

Sol Boucher 32532ac92d cbfstool: Make update-fit action work on new-style images
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.

Patrick Georgi b890a1228d Remove address from GPLv2 headers
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.

Sol Boucher 67d5998d97 cbfstool: Support top-aligned addresses for new-format images
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.

Sol Boucher 67a0a864be cbfstool: New image format w/ required FMAP and w/o CBFS master header
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.

produce an FMAP section from an fmd file having raw sections and
multiple CBFSes, pass the resulting file to cbfstool create -M -F,
then try printing its layout and CBFSes' contents, add and remove CBFS
files, and read and write raw sections.

Sol Boucher 023e829423 fmaptool: Add listing of annotated CBFS sections and generate header
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.

Sol Boucher e3260a042f cbfstool: Restructure around support for reading/writing portions of files
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.

TEST=Build panther and nyan_big coreboot.rom images with and without this patch
and diff their hexdumps. Ensure that no differences occur at different locations

Sol Boucher 1a3349ffd1 cbfstool: Simplify the common buffer_splice() function's interface
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.
