Scott Duplichan 8fed77ae4c ASRock E350M1: Configure SB800 GPP ports to support onboard pcie nic
Scott Duplichan's patch from the mailing list:
sb800 cimx wrapper: Run the complete sb800 cimx sbBeforePciInit() function
once, after determining device 0x15 function enables.

1) Update the asrock e350m1 devicetree.cb to match the hardware.
2) Change the way the sb800 cimx wrapper code works. The original
cimx code calls sb800 cimx function sbBeforePciInit() once. When
ported to coreboot, the gpp component of this function was called
once for each gpp port, as the gpp port's enable/disable state
became known. A 05/15/2011 change makes the early gpp code run
only once, triggered by processing the 4th gpp port. This method
is not general enough because the 4th gpp port is not enabled on
all boards. With the current change, the early gpp code runs when
the first gpp port is processed. If any gpp ports are enabled, the
first must be enabled. Tested with Win7 and linux on asrock e350m1.
This change will also affect amd inagua, and has not been tested
on that board.

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:
