Martin Roth 40aa9bce7d Update amd/south_station/fadt.c with various fixes
This is a model fadt.c that I would like to use for updating
several other AMD platforms with after acceptance.

- Updated to match ACPI 3.0b specification and added comments
  to reflect that.
- Since smi_cmd is 0, remove commands that rely on it:
  acpi_enable, acpi_disable, & pstate_cnt
  Add comments to that effect.
- Changed preferred_pm_profile to SOHO Server (platform
  specific)
- The southstation platform is legacy free - Updated
  iapc_boot_arch and flags to reflect that.
- Added reset_register flag so that operating systems
  will actually use the reset_reg.  This is important
  on legacy free systems.
- Updated Generic Address Structures to use access_size
  name in the updated acpi.h.  Added access sizes to
  the structures where reasonable.
- Removed 64-bit x_firmware_ctl pointer to facs.  This was
  causing a fwts failure and windows-64 BSOD.
- Added bit width for pm2_cnt_blk and modified gpe0_blk bit
  to match the hardware.

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:
