2016-02-24Revert "cbfstool: Silence LZ4 -Wsign-compare warnings"Paul Menzel
This reverts commit 17cb0370a70ccfc2301b7974bf38d44c7271afea. It’s the wrong thing to do, to just disable the warning. The code is fixed for 32-bit user space now in Change-Id I85bee25a69c432ef8bb934add7fd2e2e31f03662 (commonlib/lz4_wrapper: Use correct casts to ensure valid calculations), so enable the warning again.

2016-02-23cbfstool: Silence LZ4 -Wsign-compare warningsJulius Werner
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.

2016-02-22cbfs: Add LZ4 in-place decompression support for pre-RAM stagesJulius Werner
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).

2016-02-12util/cbfstool: Improve heuristic for cbfs header pointer protectionPatrick Georgi
cbfstool has a routine to deal with old images that may encourage it to overwrite the master header. That routine is triggered for "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.

2016-01-28util/cbfstool: add 'compact' commandAaron Durbin
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.

2015-11-13cbfstool: Allows mixed-state fmap regions to workPatrick Georgi
When using FMAP regions (with option -r) that were generated with a master header (as done by cbfstool copy, eg. in Chrome OS' build system), there were differences in interpretation of the master header's fields. Normalize for that by not sanity-checking the master header's size field (there are enough other tests) and by dealing with region offsets properly. BUG=chromium:445938 BRANCH=tot TEST=`cbfstool /build/veyron_minnie/firmware/image.dev.bin print -r FW_MAIN_A` shows that region's directory (instead of claiming that there's no CBFS at all, or showing an empty directory).

2015-10-29cbfstool: extract rmodules as ELFs properlyAaron Durbin
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.

2015-10-29cbfstool: add ELF symbol, relocation, and string table supportAaron Durbin
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.

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.

This patch fixes compilation of cbfstool on Cygwin. As reported in http://review.coreboot.org/#/c/10027 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. This patch has no impact on non-Windows builds.
