Patrick Georgi 3d295a9afb util/cbfstool: Enable "ms-extensions" compiler flag on mingw only
The flag activates some Win32 compatibility quirks and on
clang/openbsd it enables so many of them that the code doesn't compile
anymore. Therefore move it into the "Win32 area" in that Makefile.

Hung-Te Lin 8cb45aadf7 util/cbfstool: Revise lex/yacc (bison) generation
Revise the Makefile.inc rules for generating FMD parser files.

- lex:  If --header-file is supported then the lex (usually flex) should
        also support '-o' so we don't need to do redirection (-t).

- yacc: Bison is already required by bincfg and sconfig so we
        can change the default parser compiler to Bison. That also
	allows us to use -o and --defines to override the output files.

- both: Line directives are only helpful when debugging the scanner and
        the parser, so we should remove them to get better git diff
	results  (-L for lex, -l for bison).

Also regenerated the shipped files with latest version of flex (2.6.4)
and bison (3.8.2).

Edward O'Callaghan 774dcffc36 util/cbfstool: Decouple elogtool from vboot_ref flashrom code
Currently elogtool sub-proccesses flashrom as calling libflashrom
requires a missing function from the previous flashrom release.
Pending a new release of flashrom we must continue to use subprocess.

However the current subprocess wrapper implementation lives in
vboot_reference which is a git sub-module of coreboot. This causes
all sorts of grief keeping a subprocess ABI stable from vboot_reference
when the rest of vboot_reference builds of HEAD of the flashrom tree
(i.e., using unreleased libflashrom functions). In order to not keep
finding ourseleves in a bind between the two separately moving trees
with different build environments, decouple elogtool with its own
mini copy of flashrom subprocess wrapping logic.

Squash in,

  vboot signatures for flashrom r/w helpers changed in the upstream
  commit bd2971326ee94fc5. Reflect the change here to allow vboot ref

Ricardo Quesada c2cf3946c9 util/elogtool: add tool to print elog events
Add a new tool that that prints elog events.
The tool, as input, accepts either a file with the RW_ELOG contents, or
if the file is not provided it reads the contents of RW_ELOG by calling
the "flashrom" tool.

The tool is based on "mosys eventlog list"[1]. For the moment it only
supports "list", but future commits will add additional functionality.

This commit also adds missing ELOG defines needed for the tool. These
defines are added with the rest of the ELOG defines, in
include/commonlib/bsd/elog.h

The tool is placed inside util/cbfstool. The rationale behind the
decision, is that this tool shares a lot in common with the other tools
located in cbfstool: vboot dependency, shared files like common.o and
valstr.o, and in spirit is similar to some of the tools located in
cbfstool/.

As an example, you call the tool like the following:

$ elogtool list -f rw_elog_dump.bin

Julius Werner 76dab5f98f cbfstool: Add support for platform "fixups" when modifying bootblock
To support the new CONFIG_CBFS_VERIFICATION feature, cbfstool needs to
update the metadata hash embedded in the bootblock code every time it
adds or removes a CBFS file. This can lead to problems on certain
platforms where the bootblock needs to be specially wrapped in some
platform-specific data structure so that the platform's masked ROM can
recognize it. If that data structure contains any form of hash or
signature of the bootblock code that is checked on every boot, it will
no longer match if cbfstool modifies it after the fact.

In general, we should always try to disable these kinds of features
where possible (they're not super useful anyway). But for platforms
where the hardware simply doesn't allow that, this patch introduces the
concept of "platform fixups" to cbfstool. Whenever cbfstool finds a
metadata hash anchor in a CBFS image, it will run all built-in "fixup
probe" functions on that bootblock to check if it can recognize it as
the wrapper format for a platform known to have such an issue. If so, it
will register a corresponding fixup function that will run whenever it
tries to write back modified data to that bootblock. The function can
then modify any platform-specific headers as necessary.

As first supported platform, this patch adds a fixup for Qualcomm
platforms (specifically the header format used by sc7180), which
recalculates the bootblock body hash originally added by
util/qualcomm/createxbl.py.

(Note that this feature is not intended to support platform-specific
signature schemes like BootGuard directly in cbfstool. For anything that
requires an actual secret key, it should be okay if the user needs to
run a platform-specific signing tool on the final CBFS image before
flashing. This feature is intended for the normal unsigned case (which
on some platforms may be implemented as signing with a well-known key)
so that on a board that is not "locked down" in any way the normal use
case of manipulating an image with cbfstool and then directly flashing
the output file stays working with CONFIG_CBFS_VERIFICATION.)

Julius Werner 4bfbabdb54 cbfstool: Support CONFIG_CBFS_VERIFICATION and metadata hash anchor
This patch adds support for the new CONFIG_CBFS_VERIFICATION feature to
cbfstool. When CBFS verification is enabled, cbfstool must automatically
add a hash attribute to every CBFS file it adds (with a handful of
exceptions like bootblock and "header" pseudofiles that are never read
by coreboot code itself). It must also automatically update the metadata
hash that is embedded in the bootblock code. It will automatically find
the metadata hash by scanning the bootblock for its magic number and use
its presence to auto-detect whether CBFS verification is enabled for an
image (and which hash algorithm to use).

files will work standalone without any dependencies. This is pretty
brittle (for example, CL:2084062 will break it), and could be improved
by building the whole vboot library and then linking against it.
Therefore, this patch creates a new target $(VBOOT_HOSTLIB) and includes
it as a dependency for cbfstool and ifittool.

To prevent building the vboot lib twice (one for cbfstool and the other
for futility) when building coreboot tools together, add the variable
'VBOOT_BUILD' in Makefile to define a shared build path among different
tools so that vboot files don't need to be recompiled.

Also ignore *.o.d and *.a for vboot library.

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.

doesn't do that in any headers included from cbfstool right now, but
that may change. Let's switch cbfstool to a newer version to prevent
that from becoming a problem.

Marshall Dawson 30cf155168 util/cbfstool: Add AMD BIOS compression tool for PSP
Add a utility to generate a compressed BIOS image for AMD Family 17h.

If the input is an elf file, the utility extracts the program portion
for compression.  Otherwise the file is compressed as-is.

In modern AMD systems, the PSP brings up DRAM then uncompresses the
BIOS image into memory prior to x86 beginning execution.  The PSP
supports a zlib engine, and interprets the first 256 bytes as a
header, where offset 0x14 containing the uncompressed size.  For
further details, see AMD Platform Security Processor BIOS Architecture
Design Guide for AMD Family 17h Processors (NDA only, #55758).

* Add entry to CBFS file
* Add entry to REGION
* Delete entries
* Add support for types other than 1
* Add support to dump current table

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.).

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
