[patch] fix intel 82810 onboard VGA and SDRAM functions
by Elia Yehuda July 5, 2009

July 5, 2009

This patch enables the onboard VGA found on 82810 boards and fixes the memory procedures to support different kinds of DIMMs. also, support for 82810e board had been added. The only drawback from this patch is the HAVE_HIGH_TABLES being disabled since it disables (for unknown reason) the onboard VGA. Signed-off-by: Elia Yehuda <z4ziggy(a)gmail.com>

FlashROM on VIA EPIA EN12000EG
by Sebastian Schuberth July 3, 2009

July 3, 2009

Hi, this is just to report that I succeeded reading the BIOS using FlashROM 0.9.0 from my VIA EPIA EN12000EG motherboard. I haven't tried writing the BIOS yet. The only small issue I had was that my motherboard is reported to be from the "CN" rather than the "EN" series: Calibrating delay loop... OK. No coreboot table found. Found chipset "VIA VT8237", enabling flash write... OK. Found board "VIA EPIA-CN", enabling flash write... OK. Found chip "SST SST49LF004A/B" (512 KB) at physical address 0xfff80000. Reading flash... done. I don't know if it's even technically possible to distinguish the CN and EN series, or if they are simply too close / almost identical from a chipset etc. view, but I'd be happy to help out improving this, if I can. -- Sebastian Schuberth

coreinfo compilation problem

The following is the output I get when trying to compile coreinfo. wt@mediakitchen:~/projects/coreboot/coreinfo$ make CC build/cpuinfo_module.o AS build/cpuid.S.o CC build/pci_module.o CC build/coreboot_module.o CC build/nvram_module.o CC build/bootlog_module.o CC build/ramdump_module.o CC build/lar_module.o CC build/multiboot_module.o CC build/coreinfo.o LD build/coreinfo.elf /home/wt/projects/coreboot/coreinfo/build/cpuinfo_module.o: In function `cpuinfo_module_init': cpuinfo_module.c:(.text+0x469): undefined reference to `__udivdi3' ../libpayload/bin/../lib/libpayload.a(timer.o): In function `get_cpu_speed': timer.c:(.text+0xe8): undefined reference to `__udivdi3' ../libpayload/bin/../lib/libpayload.a(printf.o): In function `print_number': printf.c:(.text+0x344): undefined reference to `__umoddi3' printf.c:(.text+0x379): undefined reference to `__udivdi3' collect2: ld returned 1 exit status make: *** [/home/wt/projects/coreboot/coreinfo/build/coreinfo.elf] Error 1 Is there something I am not doing that I should be doing?

Simple Firmware Interface?
by Robinson Tryon July 2, 2009

July 2, 2009

I just found a story in the Slashdot queue about a new Intel project called the "Simple Firmware Interface" (http://simplefirmware.org/) According to the project website, SFI is "a method for platform firmware to export static tables to the operating system (OS)" and looks to be a lightweight replacement for ACPI. I haven't found any mention of SFI on either Wikipedia or on the coreboot wiki. Does anyone have further information on the project? Thanks, --R Here's the story in the /. queue: http://slashdot.org/firehose.pl?op=view&id=4979253 Here's the link to the announcement: http://www.h-online.com/open/Intel-develops-simpler-alternative-to-ACPI-for… Looks someone from Intel will be giving a talk at Linux Symposium 2009: http://www.linuxsymposium.org/2009/view_abstract.php?content_key=82

K8 resource allocation cleanup
by Myles Watson July 2, 2009

July 2, 2009

These patches depend on the new resource allocator. Abuild tested and boot tested on SimNow, qemu, s2892, and s2895. k8_north.diff: change FX_DEVS to MAX_FX_DEVS introduce fx_devs for the number of nodes only call get_fx_devs if fx_devs == 0 change i to node_id and ii to i remove shadowed variables take out continue statements in loops go to fx_devs k8_resources.diff: combine find_iopair and find_mempair return the register number instead of a resource don't allocate resources until the allocate stage simplify amdk8_create_vga_resource and move it to read resources (It could be moved above read resources, but I was minimizing changes) allocate resources in amdk8_set_resources For each resource: See if there's already a resource for that link and node Use it if there is Otherwise allocate a new one Compact resources to get rid of extra ones in amdk8_domain_read_resources, store the base and limit in the temporary resources so it's easier to debug. tolm_test needed to be changed so it didn't find the VGA resource It could probably be changed to be > 0x100000 since any system should have 1M of RAM and this is trying to find the bottom of PCI space. tolm_test should be factored out of all northbridges In device.c, rename allocate_vga_resource to set_vga_bridge_bits and move it to the beginning of resource allocation.

[PATCH] flashrom: Add support for Hyundai HY29F002T
by Andrew Morgan July 2, 2009

July 2, 2009

Add support to flashrom for Hyundai HY29F002T on the assumption it is the same as other *29F002T chips. Running 'flashrom -r' finds the chip and reads what looks like a BIOS image, other than that it is un-tested. Signed-off-by: Andrew Morgan <ziltro(a)ziltro.com> --- Once I de-solder these chips and get some sockets fitted I can do some proper testing! Gigabyte GA-7ZXR has two of them for its DualBIOS™. Switching between chips seems to be done in software... Very useful. -- Andrew.

libpayload question
by Warren Turkal July 2, 2009

July 2, 2009

Can libpayload based binaries be launched by grub instead of a Linux kernel? I would like to write something that does something similar to lspci from the bare metal instead of within Linux. Thanks, wt

[PATCH]:AMD family 10 AM2r2 support
by Bao, Zheng July 1, 2009

July 1, 2009

Add AMD family 10 AM2r2 support. Coreboot used to take SYSTEM_TYPE as a label to tell what the socket is. The patch replaces (some of, not all) SYSTEM_TYPE with CPU_SOCKET_TYPE.
