Jens Rottmann 069795a947 FrontRunner/Toucan-AF: drop unnecessary compile time CPU model selection The first reason for selecting the CPU model at compile time was a multi-second pause if booting a single core Fusion T40R with MAX_CPUS=2. Recent tests show the pause has disappeared, someone must have fixed it. The second reason was me not knowing how to make a single vgabios image work with two different PCI IDs. Many thanks to Martin Roth for educating me! Quote: "The way to make coreboot use the same vbios for different video device IDs is through the map_oprom_vendev function. In family 14 it's in northbridge/amd/agesa/family14/amdfam14_conf.c You would name your video bios 1002,9802 in the config and all the other device/vendor IDs for the family 14h processors will fall through the initial check for the video bios and will get remapped to use that vbios. This only works if you're initializing the vbios inside coreboot. I don't know if you're using SeaBios as a payload, but if you are you can add the vbios to cbfs as vgaroms/vbios.rom and the rom will always be initialized." I'd like to add the vgabios is added as type 'optionrom' when Coreboot make adds it, however to work with SeaBios it has to be added manually with cbfstool and with type 'raw', or it will hang.

coreboot README
-------------------------------------------------------------------------------

coreboot is a Free Software project aimed at replacing the proprietary BIOS
(firmware) found in most computers.  coreboot performs a little bit of
hardware initialization and then executes additional boot logic, called a
payload.

With the separation of hardware initialization and later boot logic,
coreboot can scale from specialized applications that run directly
firmware, run operating systems in flash, load custom
bootloaders, or implement firmware standards, like PC BIOS services or
UEFI. This allows for systems to only include the features necessary
in the target application, reducing the amount of code and flash space
required.

coreboot was formerly known as LinuxBIOS.


Payloads
--------

After the basic initialization of the hardware has been performed, any
desired "payload" can be started by coreboot.

See http://www.coreboot.org/Payloads for a list of supported payloads.


Supported Hardware
------------------

coreboot supports a wide range of chipsets, devices, and mainboards.

For details please consult:

 * http://www.coreboot.org/Supported_Motherboards
 * http://www.coreboot.org/Supported_Chipsets_and_Devices


Build Requirements
------------------

 * gcc / g++
 * make

Optional:

 * doxygen (for generating/viewing documentation)
 * iasl (for targets with ACPI support)
 * gdb (for better debugging facilities on some targets)
 * ncurses (for 'make menuconfig')
 * flex and bison (for regenerating parsers)


Building coreboot
-----------------

Please consult http://www.coreboot.org/Build_HOWTO for details.


Testing coreboot Without Modifying Your Hardware
------------------------------------------------

If you want to test coreboot without any risks before you really decide
to use it on your hardware, you can use the QEMU system emulator to run
coreboot virtually in QEMU.

Please see http://www.coreboot.org/QEMU for details.


Website and Mailing List
------------------------

Further details on the project, a FAQ, many HOWTOs, news, development
guidelines and more can be found on the coreboot website:

You can contact us directly on the coreboot mailing list:
