Nico Huber 607796a4ff cbfstool: Don't use le32toh(), it's non-standard
It's a BSD function, also, we missed to include `endian.h`.

Just including `endian.h` doesn't fix the problem for everyone.
Instead of digging deeper, just use our own endian-conversion from
`commonlib`.

Patrick Georgi ecaa570b60 util/cbfstool: Enable adding precompressed files to cbfs
cbfstool ... add ... -c precompression assumes the input file to be
created by cbfs-compression-tool's compress command and uses that to add
the file with correct metadata.

When adding the locale_*.bin files to Chrome OS images, this provides a
nice speedup (since we can parallelize the precompression and avoid
compressing everything twice) while creating a bit-identical file.

Patrick Georgi c88d16baaf util/cbfstool: Add cbfs-compression-tool
cbfs-compression-tool provides a way to benchmark the compression
algorithms as used by cbfstool (and coreboot) and allows to
pre-compress data for later consumption by cbfstool (once it supports
the format).

For an impression, the benchmark's results on my machine:

measuring 'none'
compressing 10485760 bytes to 10485760 took 0 seconds
measuring 'LZMA'
compressing 10485760 bytes to 1736 took 2 seconds
measuring 'LZ4'
compressing 10485760 bytes to 41880 took 0 seconds

And a possible use for external compression, parallel and non-parallel
(60MB in 53 files compressed to 650KB on a machine with 40 threads):

$ time (ls -1 *.* |xargs -n 1 -P $(nproc) -I '{}' cbfs-compression-tool compress '{}' out/'{}' LZMA)

real	0m0.786s
user	0m11.440s
sys	0m0.044s

$ time (ls -1 *.* |xargs -n 1 -P 1 -I '{}' cbfs-compression-tool compress '{}' out/'{}' LZMA)

real	0m10.444s

Julius Werner f975e55dcd cbfs: Add "struct" file type and associated helpers
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.

the FMAP in coreboot's binaries, to avoid having to find and parse the
FMAP manually for every access. For the offset of the FMAP itself this
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).

Julius Werner 09f2921b5d cbfs: Add LZ4 in-place decompression support for pre-RAM stages
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.).

BRANCH=None
BUG=None
TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on
Oak to be about ~20ms faster (cutting load times for affected stages
almost in half).

Aaron Durbin 71c60ca482 util/cbfstool: add 'compact' command
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.

There can be an error when a cbfs file is added aligned or as

resolves this error. Though adding a file to a fixed position
while hashing is used can still lead to errors.

Patrick Georgi 9a17d04e40 cbfstool: don't rewrite param.baseaddress in cbfs_add
cbfs_add calculated a base address out of the alignment specification
and stored it in param.baseaddress.
This worked when every cbfstool invocation only added a single file, but
with -r REGION1,REGION2,... multiple additions can happen.
In that case, the second (and later) additions would have both alignment
and baseaddress set, which isn't allowed, aborting the process.

Note that line 2894 of elf.h is not indented. This is because in the

Checkpatch also rejects changing the space to a tab because that makes
it more than 80 chars. I rejected breaking the line because it makes it
even less readable. All the changes forced by checkpatch make the code
less readable.

We still add a master header for compatibility purposes, and the default
layouts don't cover anything non-coreboot (eg. IFD regions) yet.

The default layouts can be overridden by specifying an fmd file, from
which the fmap is generated.

Future work:
- map IFD regions to fmap regions
- non-x86: build minimalistic trampolines that jump into the first cbfs
  file, so the bootblock can be part of CBFS instead of reserving a
  whole 64K for it.
- teach coreboot's cbfs code to work without the master header
- teach coreboot's cbfs code to work on different fmap regions

It's compatible with x86 because the default region there resides at the
old location, so things fall in place. It also makes more complex
layouts and non-x86 layouts work with negative base addresses.

Patrick Georgi a73b93157f tree: drop last paragraph of GPL copyright header
It encourages users from writing to the FSF without giving an address.
Linux also prefers to drop that and their checkpatch.pl (that we
imported) looks out for that.

This is the result of util/scripts/no-fsf-addresses.sh with no further
editing.

Aaron Durbin 694fd13390 cbfstool: extract rmodules as ELFs properly
With the previous ELF stage extract support the resulting
ELF files wouldn't handle rmodules correctly in that the
rmodule header as well as the relocations were a part of
the program proper. Instead, try an initial pass at
converting the stage as if it was an rmodule first. If it
doesn't work fall back on the normal ELF extraction.

TEST=Pulled an rmodule out of Chrome OS shellball. Manually
     matched up the metadata and relocations.

Aaron Durbin cedcb882c1 cbfstool: add ELF symbol, relocation, and string table support
In order to convert rmodules back into ELF files one needs
to add in the relocations so they can be converted back to
rmodules. Because of that requirement symbol tables need
to be present because the relocations reference the symbols.
Additionally, symbol tables reference a string table for the
symbol names. Provide the necessary support for adding all
of those things to an ELF writer.

TEST=Extracted rmodule from a cbfs and compared with the
     source ELF file. Confirmed relocations and code sizes
     are correct.

Aaron Durbin 8e982eabfa cbfstool: merge consecutive elf sections in program segments
Instead of creating a loadable segment for each section with
SHF_ALLOC flag merge those sections into a single program
segment. This makes  more tidy readelf, but it also allows
one to extract an rmodule into an ELF and turn it back into
an rmodule.

TEST=Extracted both regular stages and rmodule stages. Compared
     against original ELF files prior to cbfs insert.

Aaron Durbin 5a1e85c405 cbfstool: create ELF files when extracting stages
Instead of dumping the raw stage data when cbfstool
extract is used on stage create an equivalent ELF file.
Because there isn't a lot of information within a stage
file only a rudimentary ELF can be created.

Note: this will break Chrome OS' current usage of extract
since the file is no longer a cbfs_stage. It's an ELF file.

TEST=Extracted romstage from rom.

Aaron Durbin 539aed0646 cbfstool: decompress stage files on extraction
In order to actually do something useful with the
resulting file after being extracted decompress stage
files' content. That way one can interrogate the
resulting file w/o having to decompress on the fly.

Note: This change will cause an unexpected change to
Chrome OS devices which package up individual stage
files in the RW slots w/o using cbfs. The result will
be that compressed stages are now decompressed.

Longer term is to turn these files into proper ELF
files on the way out.
