* layout: Make `romentry.name` a pointerNico Huber2019-06-171-3/+7
| | | | | | | | | | | This should provide more flexibility while we don't have to allocate 256B extra per layout entry.

* libflashrom: Add CPP guard to fix big-endian buildsNico Huber2019-06-141-0/+2
| | | | | | | | | | | | Calm a compiler warning on big-endian builds about the unused static flashrom_layout_parse_fmap(). The guard is ugly but gets the job done. We should forbid endian-specific code in the future, I guess.

* cli: Add error on missing IFDPatrick Rudolph2019-06-141-0/+3
| | | | | | | | | | | | | | | When no IFD is present, but the option --ifd is specified, flashrom would just exit without printing a helpful error message. Add error message that IFD could not be read or parsed. Tested on Intel platform without IFD present.

* Add support to get layout from fmap (e.g. coreboot rom)Arthur Heymans2018-10-231-0/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Flashmap, or simply fmap, is a binary data format for describing region offsets, sizes, and certain attributes and is widely used by coreboot. This patch adds support for the fmap data format version 1.1 and adds --fmap and --fmap-file arguments. Using --fmap will make flashrom to search the ROM content for fmap data. Using --fmap-file will make flashrom search a supplied file for fmap data. An example of how to update the COREBOOT region of a ROM: flashrom -p programmer --fmap -w coreboot.rom -i COREBOOT flashrom -p programmer --fmap-file coreboot.rom -w coreboot.rom -i COREBOOT The fmap functions are mostly copied from cbfstool. Currently it is made mutually exclusive with other layout options until we are more clever about this input.

* Add option to read ROM layout from IFDNico Huber2017-06-141-0/+82
| | | | | | | | | | | | | | | | | | | | | | | | | Add an option --ifd to read the ROM layout from an Intel Firmware Descriptor (IFD). Works the same as the -l option, if given, -i specifies the images to update. v2: o Rebased on libflashrom, use libflashrom interface. o Use functions from ich_descriptors.c. v3: o Move ich_descriptors.o to LIB_OBJS, thus build it independent of arch and programmers. o Bail out if we aren't compiled for little endian. o Update flashrom.8.tmpl. v4: o Incorporated David's comments. o Removed single-character `-d` option. v5: Changed region names to match the output of `ifdtool --layout ...` Change-Id: Ifafff2bf6d5c5e62283416b3269723f81fdc0fa3 Signed-off-by: Nico Huber <nico.huber@secunet.com> Reviewed-on: https://review.coreboot.org/17953 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
* Add a convenient libflashrom interfaceNico Huber2017-06-031-0/+334
This adds a minimal libflashrom interface based on the draft in the wiki. While the glue code in libflashrom.c is build on top of the existing code instead on overhauling it, the interface in libflashrom.h is supposed to be stable. So we can keep the interface and adapt internals later if favoured, without breaking clients. A new make target, libinstall, is also added. It installs libflashrom.a and libflashrom.h in lib/ and include/ dirs respectively. Hooking this into the build would break linking of the CLI and is post- poned until that got fixed. v2: Rebase and fixes by Anton Kochkov. v3: o fl_image_*() rewritten with layout support (touch only included regions). o Moved read/erase/write/verify operations to flashrom.c. o Added layout pointer and flags to the flash context. v4: Removed libflashrom.o from LIB_OBJS until CLI is adapted. v5: o Incorporated David's comments. o Added `fl_flashprog_t` as dummy parameter to hide the fact that we have global state all around, and for future-proofness ofc. v6: o Change namespace prefix to flashrom_. o Remove typedefs.
