Change in flashrom[staging]: Make read_ich_descriptors_from_dump() available in flashrom
by David Hendricks (Code Review) 07 Apr '17

07 Apr '17

Hello Nico Huber, I'd like you to do a code review. Please visit https://review.coreboot.org/19196 to review the following change. Change subject: Make read_ich_descriptors_from_dump() available in flashrom ...................................................................... Make read_ich_descriptors_from_dump() available in flashrom I didn't really know what I was doing and hope removing the #ifdefs doesn't have negative side effects. The idea is to make the functions generally available for external flashing (e.g. you might want to flash an Intel machine using an ARM device as programmer). Beware of big endian trouble, I guess. :-P Change-Id: I17f80733ab6486b8b9ce80860196195a412a38da Signed-off-by: Nico Huber <nico.huber(a)secunet.com> --- M ich_descriptors.c M ich_descriptors.h M util/ich_descriptors_tool/Makefile 3 files changed, 9 insertions(+), 27 deletions(-) git pull ssh://review.coreboot.org:29418/flashrom refs/changes/96/19196/1 diff --git a/ich_descriptors.c b/ich_descriptors.c index 90f70ee..c9e82eb 100644 --- a/ich_descriptors.c +++ b/ich_descriptors.c @@ -19,14 +19,13 @@ * Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA */ -#if defined(__i386__) || defined(__x86_64__) - #include "ich_descriptors.h" -#ifdef ICH_DESCRIPTORS_FROM_DUMP - +#ifdef ICH_DESCRIPTORS_FROM_DUMP_ONLY #include <stdio.h> #define print(t, ...) printf(__VA_ARGS__) +#endif + #define DESCRIPTOR_MODE_SIGNATURE 0x0ff0a55a /* The upper map is located in the word before the 256B-long OEM section at the * end of the 4kB-long flash descriptor. @@ -34,12 +33,9 @@ #define UPPER_MAP_OFFSET (4096 - 256 - 4) #define getVTBA(flumap) (((flumap)->FLUMAP1 << 4) & 0x00000ff0) -#else /* ICH_DESCRIPTORS_FROM_DUMP */ - +#include <string.h> #include "flash.h" /* for msg_* */ #include "programmer.h" - -#endif /* ICH_DESCRIPTORS_FROM_DUMP */ #ifndef min #define min(a, b) (a < b) ?

07 Apr '17

Hello Nico Huber, I'd like you to do a code review. Please visit https://review.coreboot.org/19191 to review the following change. 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.

Change in flashrom[staging]: Add functions to read/erase/write/verify by layout
by David Hendricks (Code Review) 07 Apr '17

07 Apr '17

Hello Nico Huber, I'd like you to do a code review. Please visit https://review.coreboot.org/19189 to review the following change. 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.

Change in flashrom[staging]: Give layouts their own type
by David Hendricks (Code Review) 07 Apr '17

07 Apr '17

Hello Nico Huber, I'd like you to do a code review. Please visit https://review.coreboot.org/19188 to review the following change. Change subject: Give layouts their own type ...................................................................... Give layouts their own type Introduce `struct fl_layout` and refactor layout.c a little, so we can reuse the layout from there and have other sources of layouts beside it. I didn't want to clutter up flash.h any more. So things went into a new layout.h.

Change in flashrom[staging]: Add a convenient libflashrom interface
by David Hendricks (Code Review) 07 Apr '17

07 Apr '17

Hello Nico Huber, I'd like you to do a code review. Please visit https://review.coreboot.org/19190 to review the following change. 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. This commit breaks build of the cli. It will be fixed with a follow-up commit. 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.
