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.

The locate command was previously being used for x86 romstage
linking as well as alignment handling of files. The add command
already supports alignment so there's no more users of the
locate command. Remove the command as well as the '-T' (top-aligned)
option.

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.

Whenever we want to add a file to CBFS with a specific alignment, we
have to do two cbfstool invocations: one to find a place for the file,
and another to actually add the file to CBFS. Get rid of this nonsense

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.

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 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.

This enables more warnings on the cbfstool codebase and fixes the

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.

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,

necessary, this limitation could be addressed later.
As with other cbfstool commands, unless explicitly specified the

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.

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.

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.

to include code for some other version of the architecture instead, all per

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.

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.

Add support for filling in the Firmware Interface Table.
For now it only supports adding microcode entries.
It takes 2 options:
1. Name of file in cbfs where the mircocode is located
2. The number of empty entries in the table.
Verified with go firmware tools. Also commented out updating
microcode in the bootblock. When romstage runs, the CPUs indicate
their microcode is already loaded.

cbfstool usage change:
"-a" for "cbfstool locate" can specify base address alignment.
To support putting a blob in aligned location (ex, microcode needs to be aligned
in 0x10), alignment (-a) is implemented into "locate" command.
Verified by manually testing a file (324 bytes) with alignment=0x10:
cbfstool coreboot.rom locate -f test -n test -a 0x10
# output: 0x71fdd0
cbfstool coreboot.rom add -f test -n test -t raw -b 0x71fdd0
cbfstool coreboot.rom print -v -v
# output: test 0x71fd80 raw 324
# output: cbfs_file=0x71fd80, offset=0x50, content_address=0x71fdd0+0x144
Also verified to be compatible with old behavior by building i386/axus/tc320
(with page limitation 0x40000):
cbfstool coreboot.rom locate -f romstage_null.bin -n romstage -P 0x40000

cbfstool usage change:
The "-a" parameter for "cbfstool locate" is switched to "-P/--page-size".
The "locate" command was used to find a place to store ELF stage image in one
memory page. Its argument "-a (alignment)" was actually specifying the page size
instead of doing memory address alignment. This can be confusing when people are
trying to put a blob in aligned location (ex, microcode needs to be aligned in
0x10), and see this:
cbfstool coreboot.rom locate -f test.bin -n test -a 0x40000
# output: 0x44, which does not look like aligned to 0x40000.
To prevent confusion, it's now switched to "-P/--page-size".
Verified by building i386/axus/tc320 (with page limitation 0x40000):
cbfstool coreboot.rom locate -f romstage_null.bin -n romstage -P 0x40000

Usage Changes: To support platforms with different memory layout, "create" takes
two extra optional parameters:
"-b": base address (or offset) for bootblock. When omitted, put bootblock in
end of ROM (x86 style).
"-H": header offset. When omitted, put header right before bootblock,
and update a top-aligned virtual address reference in end of ROM.
Example: (can be found in ARM MAkefile):

CBFS allows coreboot rom images that are only partially covered
by the filesystem itself. The intention of this feature was to
allow EC / ME / IMC firmware to be inserted easily at the beginning
of the image. However, this was never implemented in cbfstool.
This patch implements an additional parameter for cbfstool.
If you call cbfstool like this:
cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000
it will now create an 8M image with CBFS covering the last 1M of
that image.
Test:
cbfstool coreboot.rom create 8192K bootblock.bin 64 0x700000
creates an 8M image that is 7M of 0xff and 1M of CBFS.

Accessing the memory of a char array through a uint32_t pointer breaks
strict-aliasing rules as it dereferences memory with lower alignment
requirements than the type of the pointer requires. It's no problem on
x86 as the architecture is able to handle unaligned memory access but
other architectures are not.
Fix this by doing the test the other way around -- accessing the first
byte of a uint32_t variable though a uint8_t pointer.

for a suitable place in a 64kb-aligned 64kb block.
cbfstool simply prints out a hex value which is the start address of a
suitably located free memory block. That value can then be used with
cbfs add-stage to store the file in the ROM image.
It's a two-step operation (instead of being merged into cbfs add-stage)
because the image must be linked twice: First, with some bogus, but safe
base address (eg. 0) to figure out the target address (based on file
size). Then a second time at the target address.
The work flow is:
- link file
- cbfstool locate
- link file again
- cbfstool add-stage.

bad: It brings a certain amount of code duplication (some of which can be
cleaned up again, or get rid of by proper refactoring).
On the other hand now there's a very simple code flow for each command, rather
than for each operation. ie.
adding a file to a cbfs means:
- open the cbfs
- add the file
- close the cbfs
rather than
open the cbfs:
- do this for add, remove, but not for create
create a new lar
- if we don't have an open one yet
add a file:
- if we didn't bail out before
close the file:
- if we didn't bail out before
The short term benefit is that this fixes a problem where cbfstool was trying
to add a file if you gave a non-existing command because it bailed out on
known, not on unknown commands.

supports fixed location files. Some parts are salvaged
from the pre-commit version (esp. stage and payload creation),
others are completely rewritten (eg. the main loop that handles
file addition)
Also adapt newconfig (we don't need cbfs/tools anymore) and fix
some minor issues in the cbfstool-README.

cbfstool extract [FILE] [NAME]
It also factors out the csize calculation in rom_add, and fixes rom_delete so
that it can handle deleting the last entry.
