Dear coreboot readers! This is the automatic build system of coreboot. The developer "rminnich" checked in revision 4389 to the coreboot repository. This caused the following changes: Change Log: I missed three files. Signed-off-by: Jon Harrison <bothlyn(a)blueyonder.co.uk> Acked-by: Ronald G. Minnich <rminnich(a)gmail.com> Build Log: Compilation of motorola:sandpointx3_altimus_mpc7410 is still broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=4389&device=sandpointx3_al… Compilation of via:epia-m700 is still broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=4389&device=epia-m700&vend… Configuration of via:epia-n is still broken See the error log at http://qa.coreboot.org/log_buildbrd.php?revision=4389&device=epia-n&vendor=… If something broke during this checkin please be a pain in rminnich'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

Dear coreboot readers! This is the automatic build system of coreboot. The developer "rminnich" checked in revision 4386 to the coreboot repository. This caused the following changes: Change Log: Ron, Attached is the third revision of the CN400/EPIA-N(L) patch for CB V2. Patch should work against r4381 (or later ?) This version now boots all of the way through to attempting to launch a payload (I'm trying FILO right now), where it falls over with exception 6 (invalid opcode) The coreboot_table issue seems to have been automagically resolved by the latest core files. It may still be that the reason for the payload not starting is down to some issue with the tables initialising, I'll look closer at that.

Re: [coreboot] C3/CN400 Support - coreboot_tables

Ron, Attached is the third revision of the CN400/EPIA-N(L) patch for CB V2. Patch should work against r4381 (or later ?) This version now boots all of the way through to attempting to launch a payload (I'm trying FILO right now), where it falls over with exception 6 (invalid opcode) The coreboot_table issue seems to have been automagically resolved by the latest core files. It may still be that the reason for the payload not starting is down to some issue with the tables initialising, I'll look closer at that.
