Patch merged into coreboot/master: Makefile.inc: Move addition of payload rev & config to payload makefile
by gerrit＠coreboot.org 20 Dec '15

20 Dec '15

the following patch was just integrated into master: commit d4c2484cc8ea1486668315d9d6c259e844ec871e Author: Martin Roth <martinroth(a)google.com> Date: Wed Dec 16 16:09:11 2015 -0700 Makefile.inc: Move addition of payload rev & config to payload makefile These files need to be added to cbfs-files after PAYLOAD_CONFIG and PAYLOAD_VERSION have been defined. Where they were before, they didn't get added to the final build.

Patch merged into coreboot/master: soc/intel/broadwell: Init var before use, only use when needed

the following patch was just integrated into master: commit 2b2ff7fa6a9af366c1a9b8e4cb6f7f566048b0d7 Author: Martin Roth <martinroth(a)google.com> Date: Fri Dec 18 10:46:59 2015 -0700 soc/intel/broadwell: Init var before use, only use when needed root_port_init_config() pcie.c wasn't initializing a variable before passing its pointer to pch_iobp_exec(). pch_iobp_exec() wrote the uninitialized value into a register. In theory, the register would only be used if data was being written, and pch_iobp_exec() was being used to read the data, not write it, so this change shouldn't have any practical effect.

Patch merged into coreboot/master: board_status.sh: Double quote variables to prevent globbing and word splitting.

the following patch was just integrated into master: commit 9f25da1f490e3e6ce02936c8d6404c68699b5aff Author: Martin Roth <martinroth(a)google.com> Date: Thu Dec 17 12:49:15 2015 -0700 board_status.sh: Double quote variables to prevent globbing and word splitting. Quoting variables prevents word splitting and glob expansion, and prevents the script from breaking when input contains spaces, line feeds, glob characters and such. See shellcheck warning SC2086.
