2016-08-27cbfs: Add "struct" file type and associated helpersJulius Werner
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.

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.

2016-06-21fmaptool: Make base offsets absolute in fmap_config.hJulius Werner
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).

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.

2016-01-28util/cbfstool: add machine parseable printAaron Durbin
In order to more easily process the output of 'cbfstool print' with other tools provide a -k option which spits out the tab-separated header and fields: Name Offset Type Metadata Size Data Size Total Size ALIGN_UP(Offset + Total Size, 64) would be the start of the next entry. Also, one can analzye the overhead and offsets of each file more easily. Example output (note: tabs aren't in here): $ ./coreboot-builds/sharedutils/cbfstool/cbfstool test.serial.bin print -r FW_MAIN_A -k Performing operation on 'FW_MAIN_A' region...

2016-01-21cbfstool: don't rewrite param.baseaddress in cbfs_addPatrick Georgi
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.
