2017-12-19util/cbfstool: calculate cbfs file size for xip stagesAaron Durbin
The initial lookup for cbfs location for xip stages is implicitly using the ELF size assuming it's relatively equivalent. However, if the ELF that is being converted contains debug information or other metadata then the location lookup can fail because the ELF is considerably bigger than the real footprint.

2017-09-20util/cbfstool: Add "expand" command to make CBFS span an fmap regionPatrick Georgi
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). BUG=b:65853903 BRANCH=none TEST=`cbfstool test.bin expand -r FW_MAIN_A` creates a new empty file of the expected size on a Chrome OS firmware image.

2017-06-04console/flashsconsole: Add spi flash console for debuggingYouness Alaoui
If CONSOLE_SPI_FLASH config is enabled, we write the cbmem 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.

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.

2016-08-10util/cbfstool: Initialize elf_writer pointer to avoid crashJonathan Neuschäfer
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.
