The code to set the igd frequencies is written with the mobile version
of the 945 chipset in mind and seems to cause cause strange igd
related problems on the desktop versions.
Some possible problems are:
* on 800MHz fsb CPUs the igd sometimes has artifacts on the screen;
* on 800MHz fsb CPU memtest results vary a lot;
* since a commit 45e11aa0a5 "Add/Combine Broadwell Chromebooks using
variant board scheme" that does not affect this northbridge, the
display shows garbage as soon as Linux (4.8) modesets the display.
A fix is to hardcode the core display and render clocks to their
maximum, potentially also improving graphical performance.
Vendor bios on all boards in coreboot with this northbridge have the
same value in this PCI config address.
TESTED on P5GC-MX (display works fine again in Linux) and
user reports of it making GA-945GCM-S2L run more stable.

As SPI master by default decodes all of top 16MiB below

read from SPI flash even in the case DCACHE_RAM_BASE was
below the nominal 4GiB - ROM_SIZE.

The channel index is either 0 or 1. DIMMs are counted from 0

Since we have two DIMMs per channel, we have to multiply the
channel index by 2 (or shift it left by 1) to get the index
of the first DIMM in the channel. Finally, to get the offset
of a DIMM in the channel we take its index modulo 2 (again,

RW flag was added to spi_slave structure to get around a requirement on
some AMD flash controllers that need to group together all spi volatile
operations (write/erase). This rw flag is not a property or attribute of
the SPI slave or controller. Thus, instead of saving it in spi_slave
structure, clean up the SPI flash driver interface. This allows
chipsets/mainboards (that require volatile operations to be grouped) to
indicate beginning and end of such grouped operations.
New user APIs are added to allow users to perform probe, read, write,
erase, volatile group begin and end operations. Callbacks defined in
spi_flash structure are expected to be used only by the SPI flash
driver. Any chipset that requires grouping of volatile operations can
select the newly added Kconfig option SPI_FLASH_HAS_VOLATILE_GROUP and
define callbacks for chipset_volatile_group_{begin,end}.
spi_claim_bus/spi_release_bus calls have been removed from the SPI flash
chip drivers which end up calling do_spi_flash_cmd since it already has
required calls for claiming and releasing SPI bus before performing a
read/write operation.

When MRC cache is available, first read only the SPD unique
identifier bytes required to detect possible DIMM replacement.
As this is 11 vs 256 bytes with slow SMBus operations, we save
about 70ms for every installed DIMM on normal boot path.
In the DIMM replacement case this adds some 10ms per installed DIMM
as some SPD gets read twice, but we are on slow RAM training boot path
anyways.

For S3 resume path SPD is only used for DIMM replacement detection.
As this detection already fails in the case of removal/insertion of
same DIMM, we can rely on cbmem_recovery() failure alone to force
system reset in case someone accidentally does DIMM replacements while
system is suspend-to-ram stage.
Skipping DIMM replacement detection allows skipping slow SPD loading,
thus reducing S3 resume path time by 80ms for every installed DIMM.

for Ivy Bridge. I expect the differences to be an update (i.e. the set-

settings affect the PCH and not the CPU which are independent from each
