The patch looks at certain DDR configurations (dual rank/single rank) and lowers the clocks to 2T or frequency as guide suggest. It sets the DualDIMMen bit which I believe should be set for non-dual channel configs.
The patch does not implement support for three dimm configurations supported from revE.
On the other hand it should improve greatly memory stability across the 939 platform.

This is an AMD K8 + NVIDIA MCP55 + ITE IT8716F mainboard.
It has a working hda_verb.h file for HD audio, and a fanctl.c file is
used to enable the CPU fan (among others) so that we don't kill the
CPU due to excessive heat.
Even though some TODOs remain of course, it works good enough to

The files debug.asl, globutil.asl, and statdef.asl are duplicated in
many K8/Fam10h boards. However, they're neither board-specific nor
K8/Fam10h-specific nor AMD-specific, so move them to src/arch/i386/acpi.
debug.asl contains generic chunks for I/O port 0x80 handling, and debug
output over serial port (init COM port, send byte, send string, etc).
globutil.asl contains utility methods for string comparison, string length
and similar stuff.
statdef.asl contains generic ACPI bit definitions / status codes from
the ACPI spec (not board- or chipset-specific).
This patch was mostly generated by:
mkdir src/arch/i386/acpi

Here is a solution using the SSDT.
Unfortunately iasl does not resolve simple arithmetic at compile
time, so we can not use Add(DEFAULT_PMBASE, PCNTRL) in the
Processor statement.
This patch instead dynamically generates the processor statement.
I can't use the speedstep generate_cpu_entries() directly since the
cpu doesn't support speedstep.
For now the code is in the southbridge directory, but maybe it
should go into cpu/intel/ somewhere.
IIRC notebook cpus of the era can already have speedstep, so it
would probably be possible to pair the i82371eb with a
speedstep-capable cpu...
Also, I don't know if multiprocessor boards (abit bp6?) would need
to be handled differently.
Abuild-tested.

the prefix was introduced in the early v2 tree many years ago
because our old build system "newconfig" could not handle two files with
the same name in different paths like /path/to/usb.c and
/another/path/to/usb.c correctly. Only one of the files would end up
being compiled into the final image.
Since Kconfig (actually since shortly before we switched to Kconfig) we
don't suffer from that problem anymore. So we could drop the sb700_
prefix from all those filenames (or, the <componentname>_ prefix in general)
- makes it easier to fork off a new chipset
- makes it easier to diff against other chipsets
- storing redundant information in filenames seems wrong

W83627DHG:
- Add proper "virtual LDN" handling for the LDNs that need it (i.e., those
that don't have their "enable" bit in bit 0 of the 0x30 register).
- Fix various I/O masks in the pnp_dev_info[] array as per
datasheet. Add missing PNP_IRQ0 to the W83627DHG_ACPI LDN.
W83627EHG:
- Similar to W83627DHG, improve the "virtual LDN" setup a bit (it was
mostly implemented already, though).
- Add missing PNP_IRQ0 to the W83627EHG_ACPI LDN.
Also: Fix up devicetree.cb of all boards using W83627DHG/W83627EHG to adapt
for the virtual LDNs.
include/device/pnp.h: Add comment that 'function' (which refers to the
LDN and should probably be renamed later) has to be at least 16 bits
wide. In theory LDNs could use u8, but due to the virtual LDN info being
encoded in the "high byte" of 'function' it must be at least u16.
asrock/939a785gmh/romstage.c: Drop unused GPIO6_DEV.
ibase/mb899/romstage.c: Use DUMMY_DEV instead of a specific LDN (serial
port 1 in this case) to avoid confusion. The global registers
manipulated there are accessible from any LDN.

BTW, my first idea was to use an acpi method that looks up pmbase in
the pci cfg space, but when I define a method like this:
Method(TEST, 2)
{
Return (Add(Arg0, Arg1))
}
I get:
|build/mainboard/asus/p2b/dsdt.ramstage.asl 9: Processor (CPU0,
