Martin Roth (gaumless(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/8070 -gerrit commit 0d7ba66bd69879e56c7c52f9b4052cf4b49614dc Author: Martin Roth <martin.roth(a)se-eng.com> Date: Mon Dec 29 14:44:38 2014 -0700 remove vx900_int16 doxygen module/group This doxygen directive was creating a top level modules section, which had the vx900_int15 code as its only member. I do think that breaking the code into documented sections is a good plan, but in an effort to clean up the output, I'm removing this for now.

In an effort to clean up the output, I'm removing these doxygen comments.

New patch to review for coreboot: 83300f6 Doxygen: add a "simple" output config and make target
by Martin Roth 04 Jan '15

04 Jan '15

Martin Roth (gaumless(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/8068 -gerrit commit 83300f6eab202bd94312c7ec41bd6e3a4d9278cb Author: Martin Roth <martin.roth(a)se-eng.com> Date: Mon Dec 29 14:56:19 2014 -0700 Doxygen: add a "simple" output config and make target This is a doxygen target I'm using for cleaning up the coreboot doxygen output. It runs in about a minute instead of.... a lot longer, and only generates documentation for the coreboot/src directory, excluding vendorcode.

New patch to review for coreboot: 8f7b0fb Add the coreboot logo to the documentation directory

New patch to review for coreboot: 42b74d8 drivers/intel/fsp: split the UEFI HOB functions into hob.c

These seem to me like they should be in their own file, so I'm splitting them out of fsp_util.c. I'll be adding a couple more functions in the next patch. These functions should all be compliant to the Hand Off Block spec.

New patch to review for coreboot: bd2d4b8 FSP chipsets: Use macro for 32 & 64 bit signatures
by Martin Roth 04 Jan '15

04 Jan '15

Martin Roth (gaumless(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/8064 -gerrit commit bd2d4b884c4958e75104727e92473f5cf91c50b9 Author: Martin Roth <martin.roth(a)se-eng.com> Date: Fri Jan 2 19:02:44 2015 -0700 FSP chipsets: Use macro for 32 & 64 bit signatures This takes what was already being done for the MRC_DATA_SIGNATURE and turns it into a macro, then uses that macro in all of the other places a 32-bit signature is needed. The macro is extended to 64-bits to use for all of the 64-bit signatures. This just makes things easier to read and understand.

New patch to review for coreboot: acc3be7 libpayload: Introduce bit manipulation macros
by Marc Jones 04 Jan '15

04 Jan '15

Marc Jones (marc.jones(a)se-eng.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/8062 -gerrit commit acc3be7488fb4c4045ae74cbdcb2be07fc6f96f2 Author: Vadim Bendebury <vbendeb(a)chromium.org> Date: Wed Jun 4 10:43:37 2014 -0700 libpayload: Introduce bit manipulation macros Some drivers being ported to depthcharge use io bit manipulation macros. The libpayload include file seems the most appropriate place to keep these macros in. There is no common io.h file across architectures, the x86 version could be added later if required. BUG=chrome-os-partner:27784 TEST=observed ipq806x SPI driver deptcharge port (WIP) compile properly.
