Commit ef8c559e537ed10d8054ca6a72ca50e0531fde95
[nb/intel/sandybridge/report_platform: Move remaining code to sb folder]
moved reporting code to the southbridge, but missed a reference in the
non-default MRC raminit path (so testing missed it).
Remove invalid reference to fix compilation error.
Test: build google/link with MRC raminit option selected

This patch contains the parts that changed the hash of the generated binary;

pci ops happen to work on this struct device since the device_path is an union.
This patch still keeps adding the fixed resources in the pci_domain
ops since moving it to the PCI ops which could properly use the
function argument for PCI operations would require all PCI IDs to be

This makes i82801ix use the common smm southbridge code to set up smm
relocation and smi handler setup. This is needed in this change for the
the smm relocation code relies on some southbridge functions provided
in the common code. Some of the old code is kept for the Q35 qemu
target.
This also caches the TSEG region and therefore increases MTRR usage a
little in some cases.
Currently SMRR msr's are not set on model_1067x and model_6fx since this needs
the MSRR enable bit and lock set in IA32_FEATURE_CONTROL. This will be handled
properly in the subsequent parallel mp init patchset.
Tested on Thinkpad X200: boots and going to and resuming from S3 still
works fine.

Logic: If vboot is not used and the tpm is not initialized in the

globally without having setup calls in lower SoC level implementations.
* Add TPM driver in ramstage chip init which calls the tpm_setup
function.
* Purge all occurrences of TPM init code and headers.
* Only compile TIS drivers into ramstage except for vboot usage.
* Remove Google Urara/Rotor TPM support because of missing i2c driver
in ramstage.

having ROM as US. A simple copy WP->WB with uncompressed
ramstage also appeared to be twice as slow as UC->WB copy.

un-lzma takes 130 seconds instead of 45 milliseconds.

The DEVEN defines are wrong, but weren't used at all.
Fix them as they are needed by the hybrid_graphics_driver and
use the defines instead of magic values.
Tested on Lenovo T410: The IGD turns on with the correct value.

The dram controller cannot fully initialize the dram on warm
reset (receive enable calibration consistently fails) therefore
requiring cached timings.
This option is mostly useful when rebooting after having flashed a new
rom which overwrites the mrc cache region.

Libgfxinit provides a better alternative to the native C init. While
libgfxinit mandates an ada compiler, we want to encourage use of it
since it is in much better shape and is actually maintained.
This way libgfxinit also gets build-tested by Jenkins.

It looks like this hardware has a bug where the display controller
does not work properly when dram is clocked 533MHz and the channels
are configured in non-stacked mode.
The workaround is to select stacked mode in this configuration.

There seems to be a hardware bug where the combination of non-stacked
channel settings, both channels populated and 533MHz dram speed cause
the display to be unusable.
The code to actually select stacked mode based on hardware
configuration will be add in a followup patch.
This patch does the following:
* Add option to the sysinfo struct for stacked mode
* Fix programming channel 1 DRB which needs special care for the last
populated rank in stacked mode
TESTED on Intel dg41wv (with stacked mode hardcoded and dram at 533MHz)

Supported CPUs are 32-bit with PAE, so there is a little reason

DDR3 adapted a fly-by topology which allows for better signal
integrity but at the same time requires additional calibration. This
is done by settings the targeted rank in write leveling mode while
disabling output buffer on the other ranks. After that the DQS signal
gets sampled over DQ until a transition from high to low is found.
