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.

Under certain conditions, not elucidated in the BKDG,
an extra memclock of CAS write latency is required.
The only reliable way I have found to detect when this

if DQS position training fails, adding the delay and
retraining.
This is probably related in some form or another to
the badly broken DQS Write Early algorithm given

The system doesn't boot with any combination of 4G + 1G in

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
other ranks.
It turns out that the XOVER CMD/XOVER CTL enable bit for DIMM1 was
missing in program_timings(), which caused the clock offset.
Problem solution:
Add two functions to calculate XOVER CMD and XOVER CTL and use both
to set XOVER in program_timings() and dram_xover().

Under specific circumstances, for instance in low power or fanless
machines, it may be useful to cap the maximum P-state of the CPU.
Allow the maximum CPU P-state to be set via an NVRAM option.

This patch adds CC6 power save support to the AMD Family 15h
support code. As CC6 is a complex power saving state that
relies heavily on CPU, northbridge, and southbridge cooperation,
this patch alters significant amounts of code throughout the
tree simultaneously.
Allowing the CPU to enter CC6 allows the second level of turbo
boost to be reached, and also provides significant power savings
when the system is idle due to the complete core shutdown.

DRAM training accounts for most of the romstage startup time, yet
if the hardware configuration has not changed from the previous boot
the previously discovered training values are still valid. Use them
if the DIMM configuration has not changed since the last boot.
The SPD values of all installed DIMMs are hashed and stored in the S3
resume data area of the main system Flash device. If a DIMM is changed
the hash will almost certainly change as well, forcing retraining on next
boot.

Upon bootup the hardware reads at minimum 256 * 16 bytes (4Kb, or 32KB) over
I2C on a system with all DIMM slots populated. If even one of those reads
has a single flipped bit in it (due to EMI, cross coupling with another trace,
or just poor margins on some cheap DIMM) the system will hang and require a
hard reset. In practice I've seen failure rates as high as 1 failed boot in
50 due to this issue, granted with cheap DIMMs, but even so retrying the read
resolves the corruption issue.
I2C is not designed for continuous data transmission with high reliability, and
there is no hardware error checking, therefore a single retry when transferring
this amount of data makes sense.

The plugged devices on PCIe should use IOAPIC2 instead of standard
IOAPIC1. The entries in IOAPIC2 count from the end of IOAPIC1.
The unchanged code worked because the OS uses MSI instead APIC.
To test that, boot linux with parameter pci=nomsi and see if the devices
like NIC work well as they do without the booting parameter.

Tested on kontron/ktqm77 (Ivy Bridge): Booted Linux and checked the
memory regions are not reserved. Couldn't test on Sandy Bridge, due to

Most AMD hardware requires at minimum two warm resets
when booting from S5 (power off). This is uncomfortably
close to the maximum bootblock execution count, and has resulted
in unstable normal/fallback operation on some machines.
Increase the default max bootblock execution count before fallback
to 6. This translates to roughly 2 - 3 failed boots before fallback
mode will engage, with an absolute worst case of pushing the reset
button 5 times to engage fallback mode in the absence of a dedicated
recovery jumper.
