David Hendricks has submitted this change and it was merged. ( https://review.coreboot.org/17947 ) Change subject: Add Doxyfile for libflashrom documentation ...................................................................... Add Doxyfile for libflashrom documentation Reference documentation for libflashrom can be build with doxygen. With doxygen Doxyfile documentation will be put into a libflashrom-doc/ subdirectory. v2: o Updated Doxyfile with `doxygen -u Doxyfile`. o Added flashrom.c to the INPUT list.

Change in flashrom[staging]: Add a convenient libflashrom interface
by David Hendricks (Code Review) 03 Jun '17

03 Jun '17

David Hendricks has submitted this change and it was merged. ( https://review.coreboot.org/17946 ) Change subject: Add a convenient libflashrom interface ...................................................................... Add a convenient libflashrom interface 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.

Change in flashrom[staging]: Add functions to read/erase/write/verify by layout
by David Hendricks (Code Review) 03 Jun '17

03 Jun '17

David Hendricks has submitted this change and it was merged. ( https://review.coreboot.org/17945 ) Change subject: Add functions to read/erase/write/verify by layout ...................................................................... Add functions to read/erase/write/verify by layout Inspired by Lynxis' related work, this implements a foundation for layout based flash access. All operations iterate over the given layout regions. Erase and write then walk, per region, over all erase blocks in an inner loop (which might not be what we want, see note on optimization below). Special care has been taken that flash content is merged properly, in case an erase block is only partially covered by a layout region or even affects mul- tiple regions. A note on performance: In the case an erase block affects multiple regions, it will probably be read, erased and written for each region. Another approach would be to walk all erase blocks once and check for each erase block which regions it touches (i.e. for each erase block, merge data pontentially from the flash and all layout regions, then flash the combined data). That might result in cleaner code. I haven't tried it yet, though.
