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.

Jonathan Neuschäfer 5de5458c2c util/cbfstool: Initialize elf_writer pointer to avoid crash
If some error happens in cbfs_payload_make_elf, the code jumps to "out",
and elf_writer_destroy(ew) is called. This may happen before an elf
writer is allocated.
To avoid accessing an uninitialized pointer, initialize ew to NULL;
elf_writer_destroy will perform no action in this case.

Julius Werner 119dcee1dd fmaptool: Make base offsets absolute in fmap_config.h
fmaptool generates a header file used to hardcode certain values from
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).

Werner Zeh ebf732b4a5 cbfstool: Use fixed width data types for e820entry struct.
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.

Werner Zeh bbf508914d cbfstool: Initialize contents of linux_params to 0
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.

Julius Werner 17cb0370a7 cbfstool: Silence LZ4 -Wsign-compare warnings
It seems that the exact behavior of -Wsign-compare changes between GCC
versions... some of them like the commonlib/lz4_wrapper.c code, and some
don't. Since we don't have a well-defined HOSTCC toolchain this slipped
through pre-commit testing. Explicitly silence the warning to ensure
cbfstool still builds on all systems.

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).

cbfstool has a routine to deal with old images that may encourage it to

"cbfstool add-master-header" prepared images even though these are not
at risk, and - worse - destroys the chain structure (through a negative
file length), so avoid touching such images.

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.
