Peter Stuge c800eeb39b flashrom: SST25VF040B using 0x90 identification and AAI write.
SST AAI is Auto Address Increment writing, a streamed write to the flash chip
where the first write command sets a starting address and following commands
simply append data. Unfortunately not supported by Winbond SPI masters.

From July 2008.

almost three years. Let's put it somewher so people find it if they're looking
for it. Someone dare sending a late announcement to the coreboot-announce list?
:-)

Add (preliminary) support for Intel 855GME (Mobile version of the 855) chipset
to coreboot.

There are some holes in the code to be filled out, but unlike the code for the
855pm this has booted a mainboard before.

Carl-Daniel Hailfinger 90308bb752 Check the printk format string against the matching arguments. We have
this type of checking in the v3 code since ages, but v2 will happily
compile any code with bogus printk format strings and/or parameters.
This can cause real bugs and at least needs to emit a warning, if not
an
error. Go with a warning for now since most of the flagged format
strings are wrong but harmless in a 32-bit x86 environment.

Carl-Daniel Hailfinger d8aaeaa143 The DBM90T code sets bit 10 in _PSS as part of the control value, but
bit 10 is part of NewVID. That means the resulting VID is wrong and
causes the processor to crash.
The Pistachio code has the same bug.

This patch fixes the wrong setting and changes control from a magic and
incorrect unexplained value (0xE8202C00) to a combination of explained
values and shifts which has the right value (0xE8202800).

It is tested on my machine and it survived 200 changes from minimum to
maximum frequency every 100 ms under heavy load and under no load.

In the long term we want to consolidate all AMD FIDVID code into one
generic library file.

Maggie Li has tested it on her DBM690T board. It is ok.

Carl-Daniel Hailfinger 734d09e05b First part of heterogenous dualchannel support.
Do not allow non-identical DIMMs yet, but prepare the code.

Calculate tCL related settings per DIMM in a dual channel setup. The
check for compatibility will come in a later patch, but since DIMMs
still have to be identical, this does not hurt.

Factor out tRC calculation to prepare for per-DIMM calculation.

Add diagnostic messages to tRC code.

Test booted to FILO, behaviour is identical if you ignore the added
debug messages (which are switched off by default).

Carl-Daniel Hailfinger 1d72e10bb4 Refactor K8 rev F DDR2 CL timing retrieval.
This will allow usage of compatible DIMMS in a dual channel setup
instead of requiring the DIMMS to be identical.

Code impact is minimal because a large chunk of code has been moved into
a separate function with almost no changes.

Tested, yields identical results and identical logs.

Carl-Daniel Hailfinger abcddcd392 Since all K8 targets now have CONFIG_USE_PRINTK_IN_CAR enabled, using
print_* in K8 RAM init does not make sense anymore. Convert almost all
print_* to printk_*. This improves readability a lot and makes the code
shorter.

Reorder the SPD equality checks in the dual channel DIMM compatibility
checking code. This is to make sure that we know if any other mismatches
are present in the DIMM. The new order eases debugging with the old
code.
Add a comment about false negatives in that code. This needs to be
implemented correctly, but that is hard to do in an efficient way.
Check if the DIMMS in a dual channel setup have any compatible CAS
latencies.

Add better comments to explain why wrong-at-first-glance SPD CL walking
code is actually correct.

Fix a few typos.
