Alexandru Gagniuc (mr.nuke.me(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/1228 -gerrit commit 3dc96c1a685b8c5c609601229161967e571485a6 Author: Alexandru Gagniuc <mr.nuke.me(a)gmail.com> Date: Tue May 21 14:51:26 2013 -0500 NOTFORMERGE: VX900 early init, and EPIA M850 board I will split this up into pallatable chunks once the dependencies are merged. This is the patch where all VX900 development is taking place. The NOTFORMERGE modifier is here to indicate that the code ain't ready. =========================================================================== == Early initialization for VIA VX900: --------------------------------------------------------------------------- MMCONF: Works from very early ramstage. Enabling MMCONF only seems to save a few milliseconds of boot time. The plan is to change the MMCONF implementation in coreboot to allow dynamically changing the MMCONF_BASE, and then use the resource allocator to get a 256MB chunk for MMCONF. SMBUS is functional. RAMINIT: Raminit works with 1 rank, but not with several ranks. DRAM calibration when more than one DIMM is does not work well. The delay calibration strategy is to put some predefined delays for the DQ input delays, and run hardware calibration on the other three delays (DQS input, DQ/DQS output). For the future, we could change this strategy to one that uses the hardware calibration of DQ input. Unfortunately, according to my testing, the DQ input delay calibration does not work reliably. Memtest runs through the serial console. It whines about memory errors during the random test (#7), but this seems to be because it tries to use the VGA memory hole (Errors start consistently at 128MB + 768K). =========================================================================== == VX900 in ramstage: --------------------------------------------------------------------------- MP tables and IOAPIC: VX900 code enables the IOAPICs are enabled as long as they're declared in devicetree.cb. Since we rely on automatic MP table generation, if an IOAPIC is not properly declared, the code spits out an error, and continues without initializing it. LPC: Implemented LPC driver with PIC interrupt routing. VGA: Still displays garbage and/or nothing. Video BIOS depends on proprietary interrupt handlers, some of which are implemented as YABEL interrupt handlers. If run in YABEL mode, the VGA BIOS requires access to other PCI devices and direct hardware access, it seems. GRUB2 and Linux are capable of initializing the VGA post-coreboot. Linux can use the VGA normally, but hangs after a while. SATA: The controller does not support AHCI, or a compliant SATA implementation. Normally SATA is done by setting RAID mode, but then SeaBIOS will not use it to boot. The only viable option is to keep the controller in native IDE mode. SATA device detection works reliably when one drive is attached. ATA DMA mode works reliably. =========================================================================== == VIA EPIA M850 board: --------------------------------------------------------------------------- Minimal infrastructure to compile a coreboot image for this board is added. PIRQ_TABLE: Implemented, Linux can find and use irqs with "noapic acpi=off" MP_TABLE: Partially generated from devicetree.cb. Not tested. KEYBOARD WORKS!!!

This file was missing some definitions, so add them. Also turn the defines into an enum. The reason for doing this is that functions can now explicitly take an spd_memory_type as a parameter: > int do_something_with_dram(enum spd_memory_type type, ...) Which is a lot more explicit and readable than: > int do_something_with_dram(u8 type, ...) These are used in the VX900 branch.

Patch set updated for coreboot: fe72b91 util/inteltool: Extend to read various bits on VIA systems

Alexandru Gagniuc (mr.nuke.me(a)gmail.com) just uploaded a new patch set to gerrit, which you can find at http://review.coreboot.org/1430 -gerrit commit fe72b9101299ba6ff28cf99ca61a7d1a84f7307e Author: Alexandru Gagniuc <mr.nuke.me(a)gmail.com> Date: Fri Aug 10 03:55:42 2012 -0500 util/inteltool: Extend to read various bits on VIA systems Reading of configuration bits is implemented via a new featuere called "quirks". Quirks are device configurations that cannot be accessed directly. They are implemented as hierarchical configurations in the PCI or memory address spaces (index/data register pairs). Such configurations refer to hardware parameters that are board specific. Those parameters would otherwise be difficult to extract from a system running the vendor's firmware.

Patch merged into coreboot/master: 8048e74 include/cpu/amd: Align `CPU_ID_EXT_FEATURES_MSR` with other defines
by gerrit＠coreboot.org 03 Jun '13

03 Jun '13

the following patch was just integrated into master: commit 8048e740a334bb7dcf8f23662c73d0ca01e53c7f Author: Paul Menzel <paulepanter(a)users.sourceforge.net> Date: Mon May 13 18:22:23 2013 +0200 include/cpu/amd: Align `CPU_ID_EXT_FEATURES_MSR` with other defines Probably due to different (character) widths for a tab, sometimes only one tab was used for aligning the define `CPU_ID_EXT_FEATURES_MSR`. For the “correct” alignment, that means where a tab is eight characters, two tabs are necessary. Change it accordingly.

the following patch was just integrated into master: commit 1b22827cf0f190f26dcccec5ae5f36eb4972cde4 Author: Rudolf Marek <r.marek(a)assembler.cz> Date: Mon May 27 20:39:18 2013 +0200 Asus F2A85-M: Fix the _CRS PCI0 bus info On Asus F2A85-M, the Linux kernel complains that the _CRS method does not specify the number of PCI busses. [FIRMWARE BUG]: ACPI: no secondary bus range in _CRS Just put there 256. This should be part of re-factoring of the whole ACPI stuff. The same change was already done for the AMD Brazos (SB800) boards, based on commit »Persimmon DSDT: Add secondary bus range to PCI0« (4733c647) [1].
