Dear coreboot readers! This is the automatic build system of coreboot. The developer "oxygene" checked in revision 6198 to the coreboot repository. This caused the following changes: Change Log: Support Intel SCH (Poulsbo) and add iwave/iWRainbowG6 board which uses it. Compiles, but not boot tested lately. Many things missing (eg. SMM support, proper ACPI, ...) Signed-off-by: Patrick Georgi <patrick.georgi(a)coresystems.de> Acked-by: Peter Stuge <peter(a)stuge.se> Build Log: Compilation of iwave:iWRainbowG6 is still broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=6198&device=iWRainbowG6&ve… If something broke during this checkin please be a pain in oxygene'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

Re: [coreboot] [PATCH]Allow components to add files to CBFS
by Xavi Drudis Ferran 18 Dec '10

18 Dec '10

Sorry to jump into a thread I don't fully understand , but is this about having blobs in coreboot that get silently copied into the EPROM ? If I understood it correctly up to now any blob had to be opted in through Kconfig, I don't really know if the idea is to avoid Kconfig for certain binaries but the user still has to place them on the tree (so nobody is using blobs inadvertently) or are there going to be parts of coreboot without source in the svn (so someone might be using sourceless code without knowing). If the later I don't like the idea and at least I would like a huge warning "BLOBS IN HERE !!!" at the end of the make output. Again, sorry at not fully following the thread or the patch.

[ANN/PATCH]Poulsbo support for coreboot
by Patrick Georgi 18 Dec '10

18 Dec '10

Hi, attached to this mail you'll find support for the Intel Poulsbo chipset, the first iteration of their System Controller Hub (SCH) designs that integrate northbridge and southbridge into a single chip. Thanks to our work with iWave Systems, we're able to release a first version of coreboot for their system, the iW-Rainbow-G6. This also is included in this delivery. We thank iWave Systems for their porting effort. Due to the massive upstream development that happened since they started on this port, a considerable effort was necessary to integrate the Poulsbo support into current coreboot. For this reason the code might not work on the iW-Rainbow-G6 as-is. Also, a number of shortcuts were taken where the board design and its deployment allowed to, leaving a couple of features unsupported and code paths unfinished. The code was provided to us under GPL terms, which iWave Systems agrees to (as shown by them distributing coreboot in binary form), so I can sign off this patch under sections (a) (for my own changes) and (b) (for the upstream delivery) of the Developer's Certificate of Origin version 1.1. Signed-off-by: Patrick Georgi <patrick.georgi(a)coresystems.de> Regards, Patrick Georgi / coresystems GmbH

Re: [coreboot] question about post_cache_as_ram() function

> What makes you so curious about the details of CAR setup? Thank you for you detailed explanation, it helps me a lot. I was trying to fix the S3 problem on my board m2v-mx_se. Basically, it dies at setting new ESP code when I wake up the machine from S3. I am not quite understand why it dies there. That assembly code just set the new esp, and clear all registers. I didn't see any reason why booting stops there. In addition, I am also not quite understand why we need to copy data from resume_backup_memory to RAMBASE. I thought all previous state info are saved at RAM after S3 sleep. Why do we need to do back_resume() at this point(it is still at cache_as_ram step)? Thanks! Best, Fengwei
