Some types of payload segment headers do not use all fields.
If these unused fields are not initialized to 0, they can
cause problems in other software which consumes payloads.
For example, PAYLOAD_SEGMENT_ENTRY does not use the compression
field. If it happens to be a non-existent compression type,
the 'cbfstool extract' command fails.

The linux trampoline was modifying the existing GDT
to add the 0x10 and 0x18 descriptors for Linux.
This will not work when the existing GDT is in ROM.
Change the code to set up a new GDT in what we know to be
RAM.
Tested by booting a linux payload. The main reason this works
is that Linux almost immediately loads its own GDT and then
segment registers. This GDT is a very temporary bridge.
Note that none of this change used to be necessary; the coreboot
GDT was originally compatible with Linux (ca 2000);
then Linux changed.

The payload is included as is, with no special header.
The code can determine the type at runtime using the CBFS_TYPE field.
Support for parsing FIT payloads in coreboot is added in a follow on
commit.
Compression of FIT payloads is not supported, as the FIT sections might be
compressed itself.

This patch adds two minor improvements to the way cbfs-compression-tool
parses the compression algorithm type that is passed through the -t
option of the 'compress' subcommand. These improvements are intended
to prevent accidents and unexpected behavior when using the
cbfs-compression-tool, in particular in automated contexts such as a
Makefile rule.
In the first part of this patch, a return statement is inserted after
the 'if (algo->name == NULL)' check of the compress() function. This
causes the function to exit immediately and subsequently abort the
program when the algorithm type was not detected correctly. Previously,
execution would continue with the 'algo' pointer pointing to the zeroed
out stopper entry of the types_cbfs_compression[] array. The ultimate
effect of this would be to pass 0 as 'algo->type' to the
compression_function() function, which happens to be the same
enumeration value as is used for CBFS_COMPRESS_NONE, leading to a valid
compression function result that matches the behavior of no compression.
Thus, if a script calling cbfs-compression-tool compress contained a
typo in the -t parameter, it would continue running with an unintended
compression result rather than immediately exiting cleanly.
In the second part of this patch, the strcmp() function is replaced with
strcasecmp() when comparing 'algo->name' with the 'algoname' parameter
that was passed to the compress() function. strcasecmp() uses an
identical function signature as strcmp() and is thus suitable as a
drop-in replacement, but it differs in behavior: rather than only
returning a result of 0 when the two NULL-terminated input strings are
character by character identical, the strcasecmp() function applies a
weaker concept of identity where characters of the latin alphabet
(hexadecimal ranges 0x41 through 0x5a and 0x61 through 0x7a) are also
considered identical to other characters that differ from them only in
their case. This causes the -t parameter of cbfs-compression-tool
compress to also accept lowercase spellings of the available compression
algorithms, such as "lz4" instead of "LZ4" and "lzma" instead of "LZMA".
As an unintended but harmless side-effect, mixed-case spellings such as
"lZ4" or "LZmA" will also be recognized as valid compression algorithms.
(Note that since the character "4" (hexadecimal 0x34) of the "LZ4"
compression type name is not part of the above-mentioned ranges of latin
alphabet characters, no new substitutions become valid for that part of
the "LZ4" string with this patch.)

If CONSOLE_SPI_FLASH config is enabled, we write the cbmem
messages to the 'CONSOLE' area in FMAP which allows us to grab the
log when we read the flash.
This is useful when you don't have usb debugging, and
UART lines are hard to find. Since a failure to boot would
require a hardware flasher anyways, we can get the log
at the same time.
This feature should only be used when no alternative is
found and only when we can't boot the system, because
excessive writes to the flash is not recommended.
This has been tested on purism/librem13 v2 and librem 15 v3 which
run Intel Skylake hardware. It has not been tested on other archs
or with a driver other than the fast_spi.

This patch adds functionality to compile a C data structure into a raw
binary file, add it to CBFS and allow coreboot to load it at runtime.
This is useful in all cases where we need to be able to have several
larger data sets available in an image, but will only require a small
subset of them at boot (a classic example would be DRAM parameters) or
only require it in certain boot modes. This allows us to load less data
from flash and increase boot speed compared to solutions that compile
all data sets into a stage.
Each structure has to be defined in a separate .c file which contains no
functions and only a single global variable. The data type must be
serialization safe (composed of only fixed-width types, paying attention
to padding). It must be added to CBFS in a Makefile with the 'struct'
file processor.

has already been using the absolute offset from the base of the whole
ROM, but for individual CBFS sections it only used the offset from the
immediate parent FMAP region. Since the code using it intentionally has
no knowledge of the whole section tree, this causes problems as soon as
the CBFS is a child section of something not at absolute offset 0 (as is
the case for most x86 Chromebooks).

In e820entry struct, the members are defined using
standard types. This can lead to different structure size
when compiling on 32 bit vs. 64 bit environment. This in turn
will affect the size of the struct linux_params.
Using the fixed width types resolves this issue and ensures
that the size of the structures will have the same length
on both 32 and 64 bit systems.

When linux is used as payload, the parameters to the kernel are build
when cbfstool includes bzImage into the image. Since not all
parameters are used, the unused will stay uninitialized.
There is a chance, that the uninitialized parameters contain
random values. That in turn can lead to early kernel panic.
To avoid it, initialize all parameters with 0 at the beginning.
The ones that are used will be set up as needed and the rest
will contain 0 for sure. This way, kernel can deal with the
provided parameter list the right way.

This patch ports the LZ4 decompression code that debuted in libpayload
last year to coreboot for use in CBFS stages (upgrading the base
algorithm to LZ4's dev branch to access the new in-place decompression
checks). This is especially useful for pre-RAM stages in constrained
SRAM-based systems, which previously could not be compressed due to
the size requirements of the LZMA scratchpad and bounce buffer. The
LZ4 algorithm offers a very lean decompressor function and in-place
decompression support to achieve roughly the same boot speed gains
(trading compression ratio for decompression time) with nearly no
memory overhead.
For now we only activate it for the stages that had previously not been
compressed at all on non-XIP (read: non-x86) boards. In the future we
may also consider replacing LZMA completely for certain boards, since
which algorithm wins out on boot speed depends on board-specific
parameters (architecture, processor speed, SPI transfer rate, etc.).

While assembling CBFS images within the RW slots on Chrome OS
machines the current approach is to 'cbfstool copy' from the
RO CBFS to each RW CBFS. Additional fixups are required such
as removing unneeded files from the RW CBFS (e.g. verstage)
as well as removing and adding back files with the proper
arguments (FSP relocation as well as romstage XIP relocation).
This ends up leaving holes in the RW CBFS. To speed up RW
CBFS slot hashing it's beneficial to pack all non-empty files
together at the beginning of the CBFS. Therefore, provide
the 'compact' command which bubbles all the empty entries to
the end of the CBFS.

When using FMAP regions (with option -r) that were generated with a

Normalize for that by not sanity-checking the master header's size field

So it is “deteled” as the type changed. But the name was not changed to

So also adapt the name when removing a file by writing a null byte to

This can leak some space in CBFS if an old-style CBFS with native master

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

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 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.
