Changes:
- Get rid of the LiPPERT FrontRunner-AF and Toucan-AF mainboard
specific code and use the platform generic function wrapper that
was added in change
http://review.coreboot.org/#/c/2497/
AMD f14: Add SPD read functions to wrapper code
- Move DIMM addresses into devicetree.cb
- Add the ASF init that used to be in the SPD read code into
mainboard_enable()
Notes:
- The DIMM reads only happen in romstage, so the function is not
available in ramstage. Point the read-SPD callback to a generic
function in ramstage.

Here's the great news: From now on you don't have to worry about
hitting the right io.h include anymore. Just forget about romcc_io.h
and use io.h instead. This cleanup has a number of advantages, like
you don't have to guard device/ includes for SMM and pre RAM
anymore. This allows to get rid of a number of ifdefs and will
generally make the code more readable and understandable.
Potentially in the future some of the code in the io.h __PRE_RAM__
path should move to device.h or other device/ includes instead,
but that's another incremental change.

I am removing the _INI method from the AZHD device because
it does not seem to do anything and causes errors in the
FWTS[1] (Firmware Test Suite) test 'method'. The INI
method performs device specific initialization and is
run when OSPM loads a description table. It must only
access OperationRegions that have been indicated as
available by the _REG (Region) method. We do not have a
_REG method and during my testing, I added a REG method
but it did not seem to make a difference in the PCI
register space. The bit fields defined as NSDI (Disable
No Snoop), NSDO (Disable No Snoop Override), and NSEN
(Enable No Snoop Request) do not ever get written from
their default values. And writing to these bit fields
does not seem to be necessary because I did not notice
any change in audio functionality.
In an effort to clean up as many FWTS errors as possible,
I propose removing this method altogether. I have seen no
change in operation (audio works with and without this
method) and there does not seem to be any change in lspci
or dmesg.

Adding the 'WordBusNumber' macro to the PCI0
CRES ResourceTemplate in the Persimmon DSDT.
This sets up the bus number for the PCI0 device
and the secondary bus number in the CRS method.
This change came in response to a 'dmesg' error
which states:
'[FIRMWARE BUG]: ACPI: no secondary bus range in _CRS'
By adding the 'WordBusNumber' macro, ACPI can set
up a valid range for the PCIe downstream busses,
thereby relieving the Linux kernel from "guessing"
the valid range based off _BBN or assuming [0-0xFF].
The Linux kernel code that checks this bus range is
in `drivers/acpi/pci_root.c`. PCI busses can have
up to 256 secondary busses connected to them via
a PCI-PCI bridge. However, these busses do not
have to be sequentially numbered, so leaving out a
section of the range (eg. allowing [0-0x7F]) will
unnecessarily restrict the downstream busses.

change-id I44f22:

The _OSC method is used to tell the OS what capabilities
it can take control over from the firmware. This method
is described in chapter 6.2.9 of the ACPI spec v3.0.
The method takes 4 inputs (UUID, Rev ID, Input Count,
and Capabilities Buffer) and returns a Capabilites
Buffer the same size as the input Buffer. This Buffer
is generally 3 Dwords long consisting of an Errors
Dword, a Supported Capabilities Dword, and a Control
Dword. The OS will request control of certain
capabilities and the firmware must grant or deny control
of those features. We do not want to have control over
anything so let the OS control as much as it can.
The _OSC method is required for PCIe devices and dmesg
checks for its existence and issues an error if it is
not found.

The Hudson-E1's default SPI speed for normal i.e. non-fast reads is 66 MHz,
but the SST 25VF032B datasheet allows max. 25. Lower the speed to 22 MHz,
otherwise BIOS flashing fails.

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.

If you try to reset the system with outb(3,0x92), outb(4,0xcf9) or a
triple-fault it will instead crash with a messy screen. As the more common
outb(0xFE, 0x64) doesn't work with our setup, Linux will crash whenever you
ask it to reboot. Closer inspection shows that on a warm boot of Coreboot
agesawrapper_amdinitpost() always fails with error code 7. Looks like DDR3
re-init goes wrong somehow. I tried find the reason for this but was
unable to. I am convinced this is not board specific but a bug in AGESA.
In the end I had to settle for a workaround: if amdinitpost returns 7 this
patch resets the system harder with outb(0x06, 0x0cf9), after that RAM init
will succeed. As amdinitpost is early in POST this automatic reset is
quick enough not to be noticable.
I'd perfer a real fix, but that's all I have.

Step 2: change the Persimmon code to adapt it to the new board's hardware.
The Toucan-AF is a COM Express Compact Type 6 form factor embedded board:
- AMD Fusion G-T56N (1.65 GHz dual core) or T40R (1 GHz single core) APU
- 1-4 GB DDR3 memory down
- 1x VGA, 2x DisplayPort (1 switchable to LVDS)
- AMD A55E (Hudson-E1) southbridge
- 8x USB 2.0
- 4x SATA
- HD Audio (with codec on baseboard)
- NEC uPD78F0532 microcontroller on I2C ("SEMA")
- 7x PCIe2.0 x1 (1 on PEG)
- Intel I210 GbE (on APU PCIe x1, can be disabled for additional PCIe)
- 2x SST 25VF032B (SO8, soldered) 4 MB SPI flash (BIOS and failsafe BIOS)
The Toucan-AF has no SIO on board. This patch includes basic support for a
Winbond W83627DHG (PS/2, 2x RS232), because the ADLINK ExpressBase-6 used
for evaluation happens to have one. The code may have to be adapted to the
actual baseboard of the application.

Step 1: copy all files unmodified from Persimmon. This makes it much
easier later to see how the two boards actually and deliberately differ
when porting bugfixes from one to the other. Git's copy detection is
imperfect (and slow).
