2019-03-05cbfstool: Support new FMD flag "PRESERVE"Hung-Te Lin
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 BUG=chromium:936768 TEST=make; boots on x86 "google/eve" and arm "google/kukui" devices Manually added 'PRESERVE' to some FMD files, and verify (by running fmap.py) the output coreboot.rom has FMAP_AREA_PRESERVE set Change-Id: I51e7d31029b98868a1cab0d26bf04a14db01b1c0 Signed-off-by: Hung-Te Lin <hungte@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/31707 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Julius Werner <jwerner@chromium.org>

2019-03-05cbfstool: Change FMD annotation to flagsHung-Te Lin
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.

2019-03-04fmap: Add FMAP_AREA_PRESERVEHung-Te Lin
When updating firmware, we may need to preserve some sections like VPD, calibration data, ... etc. The logic can be hard-coded in updater as a list of known names, but a better solution is to have that directly declared inside FMAP area flags. To do that, the first step is to apply the changes in flash map (http://crosreview.com/1493767). A new FMAP_AREA_PRESERVE is now defined and will be set in future with new syntax in FMD parser.

However, we do have endian conversion functions in commonlib/endian.h which is available for cbfstool compilation.

2018-06-15util/cbfstool: Support FIT payloadsPatrick Rudolph
In order to support booting a GNU/Linux payload on non x86, the FIT format should be used, as it is the defacto standard on ARM. Due to greater complexity of FIT it is not converted to simple ELF format. Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'. The payload is included as is, with no special header. 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 commit. Compression of FIT payloads is not supported, as the FIT sections might be compressed itself. Starting at this point a CBFS payload/ can be either of type FIT or SELF. Tested on Cavium SoC.

This patch adds a new "rawcompress" command to cbfs-compression-tool, that works exactly the same as "compress" except that it doesn't add the custom 8-byte header to the file. This can be useful if you need to compress something into a format that coreboot's decompression routines can work with, but it's not supposed to go into CBFS.

2018-05-21cbfs-compression-tool: Fix minor edge cases in algorithm type parsingJulius Werner
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.)

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.
