http://www.coreboot.org/pipermail/coreboot/2011-March/064277.html
On some mainboards it may be neccessary to reset early during resume
from S3 if the SLFRCS register indicates that a memory channel is not
guaranteed to be in self-refresh.
On other mainboards, such as Lenovo X60 and T60, the check always
creates false positives, effectively making it impossible to resume.
The SLFRCS register is documented on page 197 of
Mobile Intel® 945 Express Chipset Family Datasheet
Document Number: 309219-006
which is publically available, and the register indicates if a memory
channel is guaranteed to be in self-refresh mode (if bit = 1), or that
a memory channel *may or may not be* in self-refresh mode (if bit = 0).
The register can thus only be used to positively learn that memory is
in self-refresh. It is not known for sure that memory is *not* in
self-refresh. The register is reset by the PWROK signal, which *should*
go low during S3, and go high again when resuming, so it is unsurprising
that SLFRCS has already been cleared when we read the register.
Sven's measurements of the CKE signal on a ThinkPad shows that memory
remains in self-refresh indefinitely, until coreboot re-initializes the
memory controller, even when SLFRCS bits were = 0.
Boards which require a warm reset when SLFRCS bits are cleared must now
explicitly enable the check in the mainboard Kconfig file.
This commit selects the new option in all existing i945 mainboards.
A follow-up commit will remove the option for ThinkPads.

The old SSDT ACPI code would only include the AGESA or the coreboot SSDT. Now
include both. AGESA generates the Pstate SSDT and the second coreboot SSDT is
for TOM and TOM2. Now, generate the coreboot SSDT instead of patching it. This
fixes some ACPI errors in Linux and Windows bluescreens.
The Persimmon acpi_tables.c is where the main changes were made and then
replicated in the other Fam14 boards. Please test the other mainbords if you
have one.

Adapted from northbridge/intel/e7501 with only minor changes.
This commit provides minimal patch from e7501 and I prefer any
cosmetic clean-up to be done after initial merge.
Due the incomplete register specifications, it is safer to have
e7505 as a separate directory in case I improve it to support
wider range of memory configurations. I have no e7501 to test with.

The hp/dl145_g1 motherboard did not work since commit
1f7d3c5672ec90f8d71907b1a07c8a87fa461047 (svn 6124). That commit added
TINY_BOOTBLOCK for amd8111 southbridge. The result was that the boot process
stopped very early (no console output whatsoever). The same symptom was
reported on other AMDK8 based boards with amd8111 southbridge chips. This
commit seems to fix the bug. It adds a bootblock.c under
src/northbridge/amd/amdk8 that calls enumerate_ht_chains. Probably the
problem was that enum_ht_chains needs to be called before the southbridge
bootblock.c function, not after.

On installing/starting Windows (tested with Win7 Ultimate)
the system crashes with a Blue Screen of Death, reporting an ACPI BIOS error.
From Scott Duplichan:
To avoid the Windows BSOD, the uninitialized value TOM1 in the SSDT
must be corrected. The attached patch does this. It uses the older
patching method, and not the (possibly preferred) AML generation
method. To simplify the patching operation, I moved the AML item
'TOM1' to the start of the SSDT. The patch also includes code to
confirm the AML variable TOM1 is at the expected offset before patching.
Also tested & working with Linux.

Comment by Peter,
The variable name "temp" unfortunately does not explain what the value
is. The commit message also does not have hints. Hopefully in the
future it's possible to also use a brief moment to improve the clarity
of the code, while it is already being fixed for some other
reason. Ie. fixing up variable names, writing particularly informative
commit messages, or of course both at the same time! :)

The current version doesn't honor TSEG, and fails to
report the correct top of RAM if IGD is disabled. This
is because it uses the BSM (base of stolen RAM) register.
In that case, we should use the TOLUD register.

expected HT3 frequency and width by matching the BUID swap list to the production BIOS. In addition, the BUID swap list has been moved into the project-specific file romstage.c for the other 13 AMD family 10h projects as well. For projects using a desktop AMD family 10h processor, pasting in the mahogany_fam10 swap list will likely allow HT3 operation. This should be confirmed on real hardware before commiting any swap list change. A different swap list will be needed for server projects. For serengeti_cheetah_fam10, a reference BIOS swap list to try is: 0x00, 0x0A, 0x00, 0x06, 0xFF, 0x0A, 0x06, 0xFF.
The patch makes these changes:
1) Remove the BUID swap list from ht_wrapper.c and put it in each of 15
romstage.c files where it is used (AMD family 10h projects).
2) Add a prototype to amdfam10.h.
3) Modify the swap list and test in real hardware for mahogany_fam10 and
kino family 10h and confirm HT3 operation for the SB link.
Abuild tested.

In fact I changed coreDelay before deleting
the code in fidvid that called it. But there're
still a couple of calls from src/northbridge/amd/amdmct/wrappers/mcti_d.c
Since the comment encouraged fixing something, I
parametrized it with the delay time in microseconds
and paranoically tried to avoid an overflow at pathological
moments.

CPU and northbridge frequency and voltage
handling for Fam 10 in SVI mode.
Looking at BKDG the process for updating
Pstate Nb vid after warn reset seemed
more similar to the codethat was there fo
pvi than the one for svi, so I called the
pvi function passing a pvi/svi flag. I don't
find documentation on why should UpdateSinglePlaneNbVid()
be called in PVI, but since I can't test it,
I leave it as it was.
This patch showed some progress beyond fidvid in my
boar,d but only sometimes, most times it just didn't
work.

CPU and northbridge frequency and voltage
handling for Fam 10 in SVI mode.
Factor out some common expressions.
Add an error message when coreboots hangs waiting for a pstate
that never comes (it happened to me), and throw some
paranoia at it for good mesure.
If I understood BKDG fam10 CPUs never need a software initiated vid transition,
because the hardware knows what to do when you just request
a Pstate change if the cpu is properly configured. In fact
unifying a little what PVI and SVI do was better for my board (SVI).
So I drop transitionVid, which I didn't understand either (why
did it have a case for PVI if it is never called for PVI ?
Why did the PVI case distinguigh cpu or nb when PVI is
theoretically single voltage plane ? ).

This affects the CMOS options iommu, ECC_memory, max_mem_clock,
hw_scrubber, interleave_chip_selects.
If they're absent in cmos.layout, a Kconfig value is used if it exists,
or a hardcoded default otherwise.
[Patrick: I changed the ramstage CMOS handling a bit, and dropped the
reliance of hw_scrubber on ECC RAM, as it has nothing to do with it -
it's the cache that's being scrubbed here.]

The current code works only with dual channel if Channel 0 uses SPD address
0x50/0x51, while the second channel has to use 0x52/0x53.
For hardware that uses other addresses (like the ThinkPad X60) this means we
get only one module running instead of both.
This patch adds a second parameter to sdram_initialize, which is an array with
2 * DIMM_SOCKETS members. It should contain the SPD addresses for every single
DIMM socket. If NULL is given as the second parameter, the code uses the old
addressing scheme.

Compiles, but not boot tested lately.
Many things missing (eg. SMM support, proper ACPI, ...)

coreboot made it kind of complicated to print a character on serial. Not quite
as complicated as UEFI, but too much for a good design. Fix it.

logic) for DDR1 memory (939 sockets). The details can be found in BKDG chapter 4.1.3.3.
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.
