Aaron Durbin 4b93a4f47a cbfstool: don't use endian to fix BSD hosts
endian.h lives in under sys on the BSDs. Replace htole32() with
swab32(htonl(..)) as a proxy for little endian operations.

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.

Aaron Durbin d7339411a9 cbfstool: provide metadata size to cbfs_locate_entry()
The cbfs_locate_entry() function had a hack in there which
assumed a struct cbfs_stage data was being added in addition
to the struct cbfs_file and name. Move that logic out to the
callers while still maintaining the logic for consistency.
The only impacted commands cbfs_add and cbfs_locate, but
those are using the default 'always adding struct cbfs_stage'
in addition to cbfs_file + name. Eventually those should be
removed when cbfs_locate is removed as cbfs_add has no smarts
related to the cbfs file type provided.

Daisuke Nojiri 8984a637c1 cbfstool: allow compression at file header level
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.

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

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.

originally disallowed the use of x86-style top-aligned addresses with

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.

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.

Sol Boucher 3e060ed112 cbfstool: Fix leak in cbfs_image struct initialization
This patches a memory leak on every struct cbfs_image creation that
was introduced by c1d1fd850e. Since that
commit, the CBFS master header has been copied to a separate buffer so
that its endianness could be fixed all at once; unfortunately, this
buffer was malloc()'d but never free()'d. To address the issue, we

Sol Boucher 0e53931fee cbfstool: Clean up in preparation for adding new files
This enables more warnings on the cbfstool codebase and fixes the
issues that surface as a result. A memory leak that used to occur
when compressing files with lzma is also found and fixed.
Finally, there are several fixes for the Makefile:
 - Its autodependencies used to be broken because the target for
   the .dependencies file was misnamed; this meant that Make
   didn't know how to rebuild the file, and so would silently
   skip the step of updating it before including it.
 - The ability to build to a custom output directory by defining
   the obj variable had bitrotted.
 - The default value of the obj variable was causing implicit
   rules not to apply when specifying a file as a target without
   providing a custom value for obj.
 - Add a distclean target for removing the .dependencies file.

Vadim Bendebury 5e273a4577 cbfstool: add a command to duplicate a cbfs instance
The new command allows to create a file where the original CBFS image
is duplicated at a different offset.

The required options of the new command are -D, the offset where the
copy CBFS header is placed, and -s, the size of the new CBFS copy.

When a CBFS is copied, the bootblock area of the source CBFS is
ignored, as well as empty and deleted files in the source CBFS. The
size of the destination CBFS is calculated as the rombase size of the
source CBFS less the bootblock size.

The copy instance can be created in the image only above the original,
which rules out the use of this new command for x86 images. If
necessary, this limitation could be addressed later.

As with other cbfstool commands, unless explicitly specified the
lowest CBFS instance in the image is considered the source. If
necessary, the user can specify the source CBFS using the -H option.

Vadim Bendebury 458a12e52b cbfstool: allow user to explicitly specify header location
There potentially could be multiple CBFS instances present in the
firmware image. cbfstool should be able to operate on any of them, not
just the first one present.

To accomplish that, allow all CBFS commands to accept the -H parameter
(which specifies the exact CBFS header location in the image).

If this parameter is specified, the image is not searched for the CBFS
header, only the specified location is checked for validity, If the
location is valid, it is considered to be the CBFS header, if not -
the tool exits with an error status.

Note, that default behavior of the tool does not change.

Julius Werner efcee767de CBFS: Automate ROM image layout and remove hardcoded offsets
Non-x86 boards currently need to hardcode the position of their CBFS
master header in a Kconfig. This is very brittle because it is usually
put in between the bootblock and the first CBFS entry, without any
checks to guarantee that it won't overlap either of those. It is not fun
to debug random failures that move and disappear with tiny alignment
changes because someone decided to write "ORBC1112" over some part of
your data section (in a way that is not visible in the symbolized .elf
binaries, only in the final image). This patch seeks to prevent those
issues and reduce the need for manual configuration by making the image
layout a completely automated part of cbfstool.

Since automated placement of the CBFS header means we can no longer
hardcode its position into coreboot, this patch takes the existing x86
solution of placing a pointer to the header at the very end of the
CBFS-managed section of the ROM and generalizes it to all architectures.
This is now even possible with the read-only/read-write split in
ChromeOS, since coreboot knows how large that section is from the
CBFS_SIZE Kconfig (which is by default equal to ROM_SIZE, but can be
changed on systems that place other data next to coreboot/CBFS in ROM).

Also adds a feature to cbfstool that makes the -B (bootblock file name)
argument on image creation optional, since we have recently found valid
use cases for CBFS images that are not the first boot medium of the
device (instead opened by an earlier bootloader that can already
interpret CBFS) and therefore don't really need a bootblock.

Ronald G. Minnich 5f43184349 cbfstool: add aarch64 as a name
The aarch64 is not really an arm variant, it's sufficiently
different that it can be considered (for purposes of cbfs, certainly)
to be a new architecture.

Add a constant in cbfs.h and strings to correspond to it.
Note that with the new cbfstool support that we added earlier,
the actual use of aarch64 ELF files actually "just works" (at
least when tested earlier).

Stefan Reinauer 8f50e53a4b cbfstool: Fix architecture check when adding payload
In the process of rewriting cbfstool for ARM and using
a new internal API a regression was introduced that would
silently let you add an ARM payload into an x86 CBFS image
and the other way around. This patch fixes cbfstool to
produce an error in that case again.

Gabe Black 51edd54738 ARM: Generalize armv7 as arm.
There are ARM systems which are essentially heterogeneous multicores where
some cores implement a different ARM architecture version than other cores. A
specific example is the tegra124 which boots on an ARMv4 coprocessor while
most code, including most of the firmware, runs on the main ARMv7 core. To
support SOCs like this, the plan is to generalize the ARM architecture so that
all versions are available, and an SOC/CPU can then select what architecture
variant should be used for each component of the firmware; bootblock,
romstage, and ramstage.

ARM: Split out ARMv7 code and make it possible to have other arch versions.

We don't always want to use ARMv7 code when building for ARM, so we should
separate out the ARMv7 code so it can be excluded, and also make it possible
to include code for some other version of the architecture instead, all per
build component for cases where we need more than one architecture version
at a time.

The tegra124 bootblock will ultimately need to be ARMv4, but until we have
some ARMv4 code to switch over to we can leave it set to ARMv7.

Rather than  using [hn]to[nh] whenever accessing a member of the CBFS
header, deserialize the header when opening the CBFS image. The header
is no longer a pointer inside the CBFS buffer, but a separate struct,
a copy of the original header in a host-friendly format. This kills
more of the ntohl usage.

Ronald G. Minnich a8a133ded3 Add section header parsing and use it in the mk-payload step
This completes the improvements to the ELF file parsing code.  We can
now parse section headers too, across all 4 combinations of word size
and endianness. I had hoped to completely remove the use of htonl
until I found it in cbfs_image.c. That's a battle for another day.

There's now a handy macro to create magic numbers in host byte order.
I'm using it for all the PAYLOAD_SEGMENT_* constants and maybe
we can use it for the others too, but this is sensitive code and
I'd rather change one thing at a time.

To maximize the ease of use for users, elf parsing is accomplished with
just one function:

int
elf_headers(const struct buffer *pinput,
	    Elf64_Ehdr *ehdr,
	    Elf64_Phdr **pphdr,
	    Elf64_Shdr **pshdr)

which requires the ehdr and pphdr pointers to be non-NULL, but allows
the pshdr to be NULL. If pshdr is NULL, the code will not try to read
in section headers.

To satisfy our powerful scripts, I had to remove the ^M from an unrelated
microcode file.

TEST=Build a peppy image (known to boot) with old and new versions and verify they are bit-for-bit the same. This was also fully tested across all chromebooks for building and booting and running chromeos.
