[LinuxBIOS] Add initial support for intel i855gme northbridge
by Jon Dufresne Jan. 20, 2009

Jan. 20, 2009

Add initial support for i855gme. This is a work in progress and I don't expect it to work on all boards, or even any besides mine. This is based heavily on i855pm. Signed off by Jon Dufresne <jon.dufresne(a)gmail.com>

[LinuxBIOS] [RFC] i82801 generic patch
by Corey Osgood Dec. 30, 2007

Dec. 30, 2007

The attached patch is a unified version of the current ports of the i82801 series currently in LinuxBIOS. Since most of the ports are nearly identical, I've taken for each file and chosen the cleanest or best version of the code, then checked over the datasheets to *some* of the series, including the aa, ba, ca, and db, to make sure that it would work. I've also made some changes here and there, mostly cleanup and clarification. The only things left to look at are the huge difference between this version's lpc init and the i82801er's, finding a better way to select which chip is present on the board, and gpl headers in all files. Anyways, comments, suggestions, even flames are welcome ;) Testing on other chips can be done at this point as well, this is tested and working on one model, the i82801aa. -Corey

[LinuxBIOS] [PATCH] Remove Bitworks IMS
by Corey Osgood Dec. 1, 2007

Dec. 1, 2007

Well, as there seems to be a lot of cleaning up going on lately, might as well add this to the docket. The attached patch removes the Bitworks IMS, as 1) there's no video support for it, 2) no one objected when this was discussed previously, and 3) no one seems to have one, and they aren't readily available. Any comments are welcome. Signed-off-by: Corey Osgood <corey_osgood(a)verizon.net>

[LinuxBIOS] EFI Payload help: how to identify the resource types and attributes in LB
by Xiong Yi Sept. 25, 2007

Sept. 25, 2007

Hi, all I am developing the EFI payload for LB (see http://code.google.com/soc/2007/coresystems/appinfo.html?csaid=83B941F46A422 F1A). And I am unifying the resource management of LB and EFI. In more details, I am parsing the LB table and converting it to the HOB structures of Tiano EFI. I described this idea several days ago. (http://www.linuxbios.org/pipermail/linuxbios/2007-June/022340.html) But there is a problem: The Tiano EFI describes the system resources as types and attributes, such as the following definition: //********************************************************* // EFI_RESOURCE_TYPE (define the resource type) //********************************************************* typedef UINT32 EFI_RESOURCE_TYPE; #define EFI_RESOURCE_SYSTEM_MEMORY 0x00000000 (system memory resource) #define EFI_RESOURCE_MEMORY_MAPPED_IO 0x00000001 (memory-mapped IO) #define EFI_RESOURCE_IO 0x00000002 (Processor IO space) #define EFI_RESOURCE_FIRMWARE_DEVICE 0x00000003 (Memory-mapped firmware device) #define EFI_RESOURCE_MEMORY_RESERVED 0x00000005 (Reserved memory address space) #define EFI_RESOURCE_IO_RESERVED 0x00000006 (Reserved IO address space) //************************************************************************** ******** // EFI_RESOURCE_ATTRIBUTE_TYPE(define the resource attributes) //************************************************************************** ******** typedef UINT32 EFI_RESOURCE_ATTRIBUTE_TYPE; // These types can be ORed together as needed. #define EFI_RESOURCE_ATTRIBUTE_PRESENT 0x00000001 (the memory region exists) #define EFI_RESOURCE_ATTRIBUTE_INITIALIZED 0x00000002 (the memory region has been initialized) #define EFI_RESOURCE_ATTRIBUTE_TESTED 0x00000004 (the memory region has been tested) And there are similar definitions in the LB's /src/include/device/resourch.h file. But I can just find IORESOURCE_MEM | IORESOURCE_CACHEABLE (system memory) resources types and LB_MEM_RAM, LB_MEM_TABLE attributes in the LB tables. So how to identify other resource types and attributes in LB? Or the current LB implementation just describes these types and attributes, I need to construct the rest resource types and attributes in the payload itself as the exact requirement? By the way, I built the LB with qemu emulation and just track qemu emulation LB's source codes. Thanks & Best regards, Xiong Yi

[LinuxBIOS] [patch] flashrom: add support for Asus P5A
by Luc Verhaegen Aug. 26, 2007

Aug. 26, 2007

Here's the chip_enable code for the ALI M1533 and the board_enable for the Asus P5A, an ALI M1541+M1533 socket 7 motherboard. It's quite nasty: It does an SMBUS read/write to a yet unidentified device, i think it is the superio, but i'm not sure. The Asus P5A also seriously messes up pci-ids, there is nothing dependable there, so people who want to use flashrom on this board should use -m asus:p5a but it works :) This is a board i own myself and this has been tested successfully.

[LinuxBIOS] [patch 0/5] LAR improvements (V2)
by jordan.crouse＠amd.com Aug. 20, 2007

Aug. 20, 2007

Hey all. Following is a refresh of the LAR improvements that I posted earlier. This revision includes fixes for comments from the mailing list, bugs I discovered while integrating the code into buildROM, and last (but not least), Doxygen style comments. I know some of this code got ACKed last time I sent them out, but the messages were flying about left and right, and I figured it would just be easier to re-send them all. Also, not pictured here is the "remove-files" patch - I'll integrate it with the add-stream.patch when I commit the code, but since it just removes code, it isn't interesting to you guys. Keep an eye out for the buildROM v3 enhancements, coming soon to a mailing list near you. Following that, I have some plans for future LAR work - including the manifest stuff we discussed earlier, as well as possible replace/delete support in the LAR utility. Enjoy, Jordan -- Jordan Crouse Systems Software Development Engineer Advanced Micro Devices, Inc.
