Also update the dispatch logic in libflashrom to call wp code when status register access functions are provided by an opaque master.

* libflashrom: Return progress state to the library userRichard Hughes2022-05-251-0/+19
| | | | | | | | | | | | | | | | | | | | | | Projects using libflashrom like fwupd expect the user to wait for the operation to complete. To avoid the user thinking the process has "hung" or "got stuck" report back the progress complete of the erase, write and read operations. Add a new --progress flag to the CLI to report progress of operations. Include a test for the dummy spi25 device.

* libflashrom: Move documentation to headerEvan Benn2022-05-061-308/+0
| | | | | | | | | | | | | | | | | | | | | The doxygen documentation was in the libflashrom.c file. Move the documentation to the libflashrom.h file. This allows foreign function interface binding generators (eg rust bindgen) that operate on the .h file to generate documentation for the target language. Some doxygen errors were also corrected, mostly undocumented or wrongly labeled parameters. To test, I have diffed and inspected the doxygen documentation before and after the change. All functions are documented the same, and the structs and enums are now also included in the docs.

* libflashrom,linux_mtd: add linux_mtd writeprotect supportNikolai Artemiev2022-04-051-16/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds a generic framework to allow opaque programmers to implement writeprotect operations and uses the framework to support writeprotect operations on linux MTD device files. The generic framework comprises three new functions in `struct opaque_master` that are called from libflashrom: - wp_write_cfg() - wp_read_cfg() - wp_get_ranges() For linux_mtd, only the read/write functions are implemented. Linux's MTD interface doesn't provide a way to get available ranges, so calling get_wp_ranges() on the linux_mtd master will return FLASHROM_WP_ERR_RANGE_LIST_UNAVAILABLE.

* libflashrom/fmap: Don't use off_t for flash offsetsJulius Werner2022-02-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | off_t is a special POSIX type that is used to represent file offsets in certain APIs (e.g. lseek(), mmap()), and should not be reused to represent anything else (such as flash offsets). In particular, the width of the type may change based on the definition of the _FILE_OFFSET_BITS macro. Using such a type at the libflashrom interface is particularly dangerous, because if a program is built with a different _FILE_OFFSET_BITS value than libflashrom, the resulting ABI corruption will cause very very nasty and confusing bugs. This patch replaces all instances of off_t that are not related to file offsets with (s)size_t. BUG=b:219811851 TEST=`elogtool list` on cherry.

* 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.
