Improved version of
I1a115a45d5febf351d89721ece79eaf43f7ee8a0
The first version wasn't well tested due to the lack of hardware
and it was to aggressive.
With timC being direct function of timB's 6 LSBs it's critical to match
timC and timB.
Some tests increments the value of timB by a small value,
which might cause the 6bit value to overflow, if it's close
to 0x3F.
Increment the value by a small offset if it's likely
to overflow, to make sure it won't overflow while running
tests and bricks the system due to a non matching timC.
In comparission to the first attempt, only 4 out of 128 timB values
are considered bad.
Needs test on real hardware !
Fixes a "edge write discovery failed" on my test system.

* Gigabyte GA-B75M-D3H

Some vendors store lower frequency profiles in the regular SPD,
if the SPD contains a XMP profile. To make use of the board's and DIMM's
maximum supported DRAM frequency, try to parse the XMP profile and
use it instead.
Validate the XMP profile to make sure that the installed DIMM count
per channel is supported and the requested voltage is supported.
To reduce complexity only XMP Profile 1 is read.
Allows my DRAM to run at 800Mhz instead of 666Mhz as encoded in the
default SPD.

Issue observed:
The PCIe Root port shows up in GNU/Linux but no PCIe device
is being detected.
Test system:
* Gigabyte GA-B75M-D3H (Intel Pentium CPU G2130)
* Lenovo T530 (Intel Core i5-3320M CPU)
Problem description:
The PEG Root port link training on Ivy Bridge needs to be manually started.
Problem solution:
The bits are set in early_init to meet PCIe reset timeout of 100msec.
The bits should be set in PCI device enable function, but this causes the
PCI enumeration to not detect the card, as it's still booting. Adding
a fixed delay of 100msec resolves this problem, but this would
increase boot time.
Read the PCI base revision mask to make sure it's any IvyBridge CPU.
Don't run the code on MRC path as it has its own PEG initilization code.
Tested with:
* Nvidia NVS 5400M (PCIe2)
* ATI Radeon HD4780 (PCIe2)
* Nvidia GeForce 8600 GT (PCIe1)
Untested:
* PCIe3 devices
Final test results:
The PEG device shows up under GNU/Linux and can be used without issues.

We want the question for CBFS size to be next to the rom size in the
mainboard directory, but that doesn't seem to work for how people
want to set the defaults. Instead of having the list of exceptions
to the size, just set the defaults at the end of kconfig.
- Move the defaults for chipsets not setting HAVE_INTEL_FIRMWARE into
the chipset Kconfigs (gm45, nehalem, sandybridge, x4x)
- Override the default for HAVE_INTEL_FIRMWARE on skylake.
- Move the HAVE_INTEL_FIRMWARE default setting into the firmware
Kconfig file
- Move the location of the default CBFS_SIZE=ROM_SIZE to the end of
the top level kconfig file, while leaving the question where it is.
Test=rebuild Kconfig files before and after the change, verify that
they are how they were intended to be.
Note: the Skylake boards actually changed value, because they were
picking up the 0x100000 from HAVE_INTEL_FIRMWARE instead of the
0x200000 desired. This was due to the SOC_INTEL_SKYLAKE being after
the HAVE_INTEL_FIRMWARE default. Affected boards were:
Google chell, glados, & lars and Intel kunimitsu.

The find the issue I X-Y plotted timC vs timB for every
lane on the failing rank.
You can see an offset by 32 units for timB, that is not present on

It turns out that the XOVER CMD/XOVER CTL enable bit for DIMM1 was
missing in program_timings(), which caused the clock offset.
