Dear coreboot readers! This is the automatic build system of coreboot. The developer "stepan" checked in revision 4308 to the coreboot repository. This caused the following changes: Change Log: encapsule mbi initialization in write_multiboot_table, where it belongs. (very simple and trivial) Signed-off-by: Stefan Reinauer <stepan(a)coresystems.de> Acked-by: Stefan Reinauer <stepan(a)coresystems.de> Build Log: Compilation of embeddedplanet:ep405pc is still broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=4308&device=ep405pc&vendor… Compilation of motorola:sandpointx3_altimus_mpc7410 is still broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=4308&device=sandpointx3_al… Compilation of totalimpact:briq is still broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=4308&device=briq&vendor=to… If something broke during this checkin please be a pain in stepan'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] reentrant and .bss-less vsprintf
by Patrick Georgi 27 May '09

27 May '09

Hi, attached patch kills a global variable, and makes vsprintf reentrant and work without requiring .bss space. Make vsprintf reentrant. More importantly, eliminate global variable.

[PATCH] Remove scanbuild warning in hypertransport.c
by Myles Watson 27 May '09

27 May '09

Scanbuild finds a possible null pointer dereference here: http://www.coreboot.org/~stepan/coreboot-scanbuild/kontron_986lcd-m-scanbui… There are two ways that I thought of fixing it. The first way is just to insert an if (first == NULL) return NULL; at line 53 and remove the if (first) condition. The only problem with that is that it makes the change look bigger than it is. Here's a simpler looking change. Either one is fine with me. Boot tested on s2892. Signed-off-by: Myles Watson <mylesgw(a)gmail.com> Thanks, Myles

Author: oxygene Date: 2009-05-26 16:49:59 +0200 (Tue, 26 May 2009) New Revision: 4309 Modified: trunk/coreboot-v2/src/arch/i386/lib/console_printk.c Log: Make printk_* behaviour more consistent. Without it, side effects in the arguments (eg. a pci config read, or variable increment) "vanish" with the message, and the behaviour changes. Some of these effects might be unwanted, but at least they are consistent now. To reduce the memory footprint slightly, the formatted strings are discarded.
