Dear coreboot readers! This is the automatic build system of coreboot. The developer "myles" checked in revision 5192 to the coreboot repository. This caused the following changes: Change Log: Remove redundant run_bios prototype. Trivial.

Author: stepan Date: Fri Mar 5 11:03:50 2010 New Revision: 5185 URL: http://tracker.coreboot.org/trac/coreboot/changeset/5185 Log: This patch is from 2009-10-20 Convert all DEBUG_SMBUS, DEBUG_SMI, and DEBUG_RAM_SETUP custom and local #defines into globally configurable kconfig options (and Options.lb options for as long as newconfig still exists) which can be enabled by the user in the "Debugging" menu. The respective menu items only appear if a board is selected where the chipset code actually provides such additional DEBUG output. All three variables default to 0 / off for now. Also, drop a small chunk of dead/useless code in the src/northbridge/via/cn700/raminit.c file, which would otherwise break compilation.

build service results for r5191
by coreboot information March 5, 2010

March 5, 2010

Dear coreboot readers! This is the automatic build system of coreboot. The developer "myles" checked in revision 5191 to the coreboot repository. This caused the following changes: Change Log: 1. Move run_bios prototype to device.h 2. Use time.h for get_time() and move tb_freq into functions.c 3. Move read_io and write_io to io.c and make them static 4. Make a couple of functions static in interrupt.c 5. Refactor a cast from char[] to u64 to get rid of potential alignment problems and a warning Signed-off-by: Myles Watson <mylesgw(a)gmail.com> Acked-by: Stefan Reinauer <stepan(a)coresystems.de> Build Log: Compilation of emulation:qemu-x86 has been broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=5191&device=qemu-x86&vendo… If something broke during this checkin please be a pain in myles's neck until the issue is fixed. If this issue is not fixed within 24h the revision should be backed out. Best regards, coreboot automatic build system

[PATCH] YABEL compilation warnings
by Myles Watson March 5, 2010

March 5, 2010

This patch removes most of the rest of the compilation warnings for me. 1. Move run_bios prototype to device.h 2. Use time.h for get_time() 3. Move read_io and write_io to io.c and make them static 4. Make a couple of functions static in interrupt.c 5. Refactor a cast from char[] to u64 to get rid of potential alignment problems and a warning The only ones left are "unused" warnings. I think we should get rid of that warning, since we conditionally call functions based on debugging and various config variables. Is there a case where it helps enough to justify all the warnings? This next part isn't part of the patch, but applying it makes qemu compile with yabel (with and without debugging).
