[PATCH] Fix bayou payload execution
by Ulf Jordan 10 Feb '09

10 Feb '09

Bayou svn HEAD cannot execute its payloads correctly, due to payloads overwriting bayou in memory. This is in turn due to the lpgcc link run trying to apply both libpayload's and bayou's ldscripts. The two attached patches a) makes lpgcc's choice of ldscript overridable and b) adjusts bayou's ldscript to work with the recent MB changes in libpayload. Compile and runtime tested with bayou, coreinfo and coreboot-v3 in QEMU. /ulf

Author: myles Date: 2009-02-10 22:12:35 +0100 (Tue, 10 Feb 2009) New Revision: 3935 Modified: trunk/payloads/libpayload/bin/lpgcc Log: Fix bayou payload execution. Bayou must link with its own ldscript to end up at a load address that doesn't interfere with payloads. Make Bayou's ldscript MB compatible, so the link with libpayload/lib/i386/head.o succeeds.

seabios question
by ron minnich 10 Feb '09

10 Feb '09

Sorry, I'm new to all this and am under ugly deadlines so I'm again asking for help. I need to run gpxe. Gpxe needs a bios api. So I need to put together coreboot v2 + seabios + gpxe. This is a bit more than I've done and I wonder if someone has done it already. This needs to all be in ROM. The goal is to have a kontron booting LTSP or whatever we want, and gpxe is ideal for this purpose. I need v2 for SMP, SMI, and ACPI. Thanks in advance ... ron

Move Plugin support options

Plugin support shouldn't be as visible as it is. This patch moves it to the device menu and makes it depend on expert. Signed-off-by: Myles Watson <mylesgw(a)gmail.com> Thanks, Myles

flashrom: Can't mmap memory
by Myles Watson 09 Feb '09

09 Feb '09

When I boot using the factory BIOS on my s2895 flashrom works. When I boot with Coreboot, I get the Error: Can't mmap memory using /dev/mem: Operation not permitted It shouldn't be kernel parameters since I'm using the same grub2 entry to boot either way. This sounds a little too familiar, but I can't find a thread where this isn't linked to a newer, more restrictive kernel. Thanks, Myles

The logic for that was incorrectly triggered also when a board had more than one flash chip. This patch will honor flashbase only when probing for the first flash chip on the board, and look at top of 4GB for later … [View More]
