This is the automated build check service of coreboot.

the coreboot source repository and caused the following 
changes:

Change Log:

Build Log:
Compilation of amd:serengeti_cheetah_fam10 is still broken
See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=3100&device=serengeti_c...

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.
