Fix two out-of-bounds reads in lz4 decompression:
1) LZ4_decompress_generic could read one byte past the input buffer when
decoding variable length literals due to a missing bounds check. This
issue was resolved in libpayload, commonlib and cbfstool
2) ulz4fn could read up to 4 bytes past the input buffer when reading a
lz4_block_header due to a missing bounds check. This issue was resolved
in libpayload and commonlib.

Newest clang compilers warn about "misleading indentation", and because
warnings-are-errors in our builds, that breaks the build.
The lzma code base is vendored in, so we might just have to update it,
but that's a bigger effort than just removing a couple of spaces (the
coding style of the file is horrible, but I will only change it as much
as the compilers ask for).

In glibc feature control macros, _DEFAULT_SOURCE is the shorthand to
tell glibc to enable "all the default stuff", meaning POSIX, BSD and
System V interfaces. However, this macro is somewhat recent and older
glibc versions (e.g. 2.12) are still occasionally in use that don't
recognize it yet. For the benefits of users with these versions, let's
also enable the deprecated _BSD_SOURCE and _SVID_SOURCE macros which
essentially achieve the same thing. We must continue to define
_DEFAULT_SOURCE so that newer glibc versions don't throw a deprecation
warning.
This patch should make BSD-style byteswap macros like le32toh()
available on these older glibc versions.

This patch creates a new commonlib/bsd subdirectory with a similar
purpose to the existing commonlib, with the difference that all files
under this subdirectory shall be licensed under the BSD-3-Clause license
(or compatible permissive license). The goal is to allow more code to be
shared with libpayload in the future.
Initially, I'm going to move a few files there that have already been
BSD-licensed in the existing commonlib. I am also exracting most
contents of the often-needed <commonlib/helpers.h> as long as they have
either been written by me (and are hereby relicensed) or have an
existing equivalent in BSD-licensed libpayload code. I am also
relicensing <commonlib/compression.h> (written by me) and
<commonlib/compiler.h> (same stuff exists in libpayload).
Finally, I am extracting the cb_err error code definitions from
<types.h> into a new BSD-licensed header so that future commonlib/bsd
code can build upon a common set of error values. I am making the
assumption here that the enum constants and the half-sentence fragments
of documentation next to them by themselves do not meet the threshold of
copyrightability.

This patch adds an optional pre-RAM cache for the FMAP which most
platforms should be able to use, complementing the recently added
post-RAM FMAP cache in CBMEM. vboot systems currently read the FMAP
about half a dozen times from flash in verstage, which will all be
coalesced into a single read with this patch. It will also help
future vboot improvements since when FMAP reads become "free" vboot
doesn't need to keep track of so much information separately.
In order to make sure we have a single, well-defined point where the new
cache is first initialized, eliminate the build-time hardcoding of the
CBFS section offsets, so that all CBFS accesses explicitly read the
FMAP.
Add FMAP_CACHEs to all platforms that can afford it (other than the
RISC-V things where I have no idea how they work), trying to take the
space from things that look like they were oversized anyway (pre-RAM
consoles and CBFS caches).

Considering the following integer multiplication:
u64 = u16 * u16
What on earth, one might wonder, is the problem with this? Well, due to
C's unfortunately abstruse integer semantics, both u16's are implicitly
converted to int before the multiplication, which cannot hold
all possible values of a u16 * u16. Even worse, after overflow the
intermediate result will be a negative number, which during the
conversion to a u64 will be sign-extended to a huge integer. Not good.
The solution is to manually cast one of the u16 to a u32 or u64, which
are large enough to not have any overflow and will prevent the implicit
conversion. The type of the u64 is preferred, though a u32 is used
instead of size_t, since that can change depending on the platform.

When updating firmware, it is very often that we may want to preserve
few sections, for example vital product data (VPD) including serial
number, calibration data and cache. A firmware updater has to hard-code
the section names that need to be preserved and is hard to maintain.
A better approach is to specify that in FMAP area flags (the `area_flag`
field) using FMAP_AREA_PRESERVE. With this patchset, a FMD parser flag
"PRESERVE" is introduced and will be converted to FMAP_AREA_PRESERVE
when generating FMAP data (by fmap_from_fmd.c).
For example, The FMD statement:
RO_VPD(PRESERVE)@0x0 16k
will generate an FMAP firmware section that:
area_name = "RO_VPD"
area_offset = 0
area_size = 16384
area_flags = FMAP_AREA_PRESERVE

The idea of "annotation" for firmware sections was pretty flexible, but
in future we will want multiple attributes applied to same area. For
example, indicate the section must be preserved when updating firmware
so serial number or MAC address can be preserved.
The solution here is to extend annotation so it can take multiple
identifiers (flags) in a row. For example, to declare a 64KB COREBOOT
section as CBFS using annotation:
COREBOOT(CBFS)@0x0 64k
If there's a new flag "PRESERVE" indicating the section must be
preserved before update, we can declare it following CBFS flag:
COREBOOT(CBFS PRESERVE)@0x0 64k
The flags are directly parsed in fmd_parser, and stored in an union
flashmap_flags. Output modules can choose to ignore or process the
flags.
Currently the only supported flag is "CBFS" (for backward compatible
with annotation). There will be more new flags in follow up patches.

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

Compression of FIT payloads is not supported, as the FIT sections might be

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.)

vboot images come with multiple regions carrying CBFS file systems. To
expedite hashing (from slow flash memory), the FW_MAIN_* regions are
truncated since they typically have pretty large unused space at the
end that is of no interest.
For test purposes it can be useful to re-engage that space, so add a
command that creates a new empty file entry covering that area (except
for the last 4 bytes for the master header pointer, as usual).

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).

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

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.

These need to go together, so the commit became a bit larger than
typial.
- Add an option -R for the copy source fmap region.
Use: cbfstool copy -r target-region -R source-region.
- Don't generate a CBFS master header because for fmap regions, we
assume that the region starts with a file header.
Use cbfstool add-master-header to add it afterwards, if necessary.
- Don't copy files of type "cbfs master header" (which are what cbfstool
add-master-header creates)
- Leave room for the master header pointer
- Remove -D command line option as it's no longer used.

The constant for ppc64 is 'hotstuff'. For many reasons.
Note that line 2894 of elf.h is not indented. This is because in the
original the line begins with a space. Checkpatch rejects that.
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.
Herman Hollerith would be proud.

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

The former interpretation sprung from the x86 way of doing things
(assuming top-alignment to 4GB). Extend the mechanism to work with CBFS
regions residing elsewhere.
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.

cbfstool on Cygwin likes to be compiled with -D_GNU_SOURCE.
That patch was abandoned because it would unwantedly turn on
more GNU extensions. Instead of doing that, only enable the
define on Cygwin, switch to -std=gnu99 instead of -std=c99 to
make fileno and strdup actually available.
A MINGW32 check that was forgotten in Makefile was copied over
from Makefile.inc to keep the two files in sync.
