8M was set in the assumption that at least 4M was needed for IED
(Intel Enhanced Debug) , but this is not true.
The SMRR MTRR's need to have TSEG aligned to its size which is easier when TSEG
is only 2M. Also at most 6M of RAM more becomes available for use.

Having cbmem floating between two ram regions is a bad idea and some

While during the read training itself only the settings for rank 0 are used for
all ranks, the controller does use the separate settings for each rank later on.
It is unknown which register is responsible for this.
The signals are probably not generated separately and therefore need to have the
same settings for all ranks. Therefore program the results for all ranks instead
of for all populated ranks.
TESTED: Fixes DG43GT not booting with only the second DIMM slot of a channel
populated.

Using the cached CPU FSB setting can simply be wrong, in which case it won't
boot. Since the selected timings also depend on the CPU FSB, it is also best to
not use cached timings at all when a change is detected.
Tested on P5QC, swapped a 1333MHz FSB to a 800MHz FSB and it uses !fast_boot
boot path.

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

This change also makes sure that the sum the uma regions (TSEG, GSM,
GSM) is 4MiB aligned. This is needed to avoid cbmem_top floating between
2 usable ram region, since cbmem_top is aligned 4MiB down to easy MTRR
setup for ramstage. At least tianocore requires this and fails to boot
without it.
Better MTRR are achieved by making the memory 'hole' till 4GiB exactly
2Gib.
This code mimics how it is done in nb/intel/gm45 and achieves similar
results.
TSEG is enabled and set to 8M since this makes it easier to reuse the
common smm setup / parallel mp code and makes it possible to cache the

This training find the optimal write DQ delay and read DQS delay
settings. It does so on all lanes at the same time, like
vendor (training each lane individually has poor results).
The results are stored in the sysinfo struct and restored on next
boots and S3 resume.
This potentially increases stability as optimal settings are chosen
and is more necessary for DDR3 raminit where the write DQS delays are
leveled/variable due to the flyby topology.
TESTED on Intel DG43GT with (2G + 1G) on each channel, see that the
results are quite close to the safe original ones (that previous
worked fine) and tested with memtest86+.

This patch pushes these large default delay tables to a different file
to reduce cluttering up the actual raminit source. While doing so it
also uses more but smaller arrays and also adds the respective default
delays for DDR3 which are not yet used in this patch.
This patch add a function to set the read DQS delays instead of just
programming magic values. (This will prove useful for DQS read
training)
To prepare for adding trainings on the delay values it stores these
default delays in the sysinfo struct to program those. Later when
trainings are implemented those trained values will be used instead of
these safe default values, via using the cached sysinfo in 'mrc'
cache.

Stores information obtained from decoding dimms and receive enable
results for future use.
Depreciates using rtc nvram to store receive enable settings.
A notable change is that receive enable results are always reused, not
just on a resume from S3.
This requires cbmem to be initialized a bit earlier, right after the
raminit finished to be able to add the sysinfo struct to cbmem which
gets cached to the SPI flash in ramstage.
TESTED on Intel DG43GT with W25Q128.V. With 4 ddr2 dimms time in

This is mostly written from scratch and uses common spd ddr2 decode
functions.
This improves the following:
* This fixes incorrect CAS/Freq detection on DDR2;
* Fixes tRFC computation; tRFC == 78 is a valid timing which is
excluded and 0 ends up being used; (TESTED)
* Timings selection does not use loops;
* Removes ddr3 spd decode and is re-added in follow-up patches using
common ddr3 spd functions;
* Raminit would bail out if a dimm was unsupported, now in some cases it
just marks the dimm slot as empty;
* It dramatically reduces stack usage since it does not allocate 4
times 256 bytes to store full SPDs, amongs other unused things that
were stored in sysinfo;
* Reports when no dimms are present;
* Uses i2c block read to read SPD which is about 5 times faster than
bytewise read, with a fallback to smbus mode in case of failure,
which does seem to happen when the system is forcefully powered
off.

Moves receive enable calibration to a separate file to lighten
raminit.c a bit.
Receive enable calibration is quite similar to gm45 so it reuses some
of its function names.
The functional changes are:
* the minimum coarse is now reset for each channel;
* on the second fine search for DQS high, TAP overflow is handled by
increasing medium;
* start coarse at CAS + 1 instead of CAS - 1. Other Intel northbridges
do the same and the results are more in line with register dumps
from vendor bios.
These might improve stability.

The x4x northbridge can be paired with either an ICH7 (in the case of
g41) or an ICH10 (all other cases: g45, q45, p45, ...). Only ICH10
sometimes occurs with a descriptor, gbe and an ME region.
ICH7 is always descriptorless so it makes no sense to fix CBFS to
accommodate for those other objects.

It rewrites the results of receive enable stored in the upper nvram
region, to avoid running receive enable again.
Some debug info is also printed about the self-refresh registers.
(Not enforcing a reset here, since 0 does not necessarily mean it's
not in self-refresh).

Previously the raminit failed on hot reset and to work around this
issue it unconditionally did a cold reset.
This has the following issues:
* it's slow;
* when the OS issues a hot reset some disk drives expect their 5V
power supply to remain on, which gets cut off by a cold reset,
causing data corruption.
To fix this some steps in raminit must be ommited on the reset path.
This includes receive enable calibration.
To achieve this it stores receive enable results in RTC nvram for them
to be rewritten on the resume path.
Note: The same thing needs to be done on the S3 resume path.
Calling a hot reset after raminit "outb(0x6, 0cf9)" works.

The results were obtained by comparing the MCHBAR registers of vendor bios
with coreboot at the same dram timings.
This fixes 2 issues:
* 1333MHz fsb CPUs were limited to 667MHz ddr2 speeds, because with
800MHz raminit failed;
* 1067MHz fsb CPUs did not boot when second dimm slot was populated.
TESTED on ga-g41m-es2l on 800, 1067 and 1333MHz CPUs with
DDR2 667 and 800MHz dimms.

Currently only there is only one eaglelake board in coreboot
(ga-g41m-es2l) featuring a G41 variant northbridge.
Adding boards with a different variant (Q43, Q45, G43, G45, B43) will
require this change for graphic initialisation.

Adapt implementation from skylake to prepare for removal of
HIGH_MEMORY_SAVE and moving on to RELOCATABLE_RAMSTAGE.
With this change, CBMEM region is set early-on as WRBACK
with MTRRs and romstage ram stack is moved to CBMEM.
