This means that any PCIe device placed in a PEG slot should now work.
During S3 resume, link training sometimes does not complete before
device enumeration. However, no tangible issues have been observed.
Fixing it would introduce a rather large delay in S3 resume.
There are a few minor shortcomings:
- Using PEG for display output is not yet supported.
- Only PEG2 is supported. An extra (unknown) training sequence is said to
be needed for PEG3.
- The ACPI _PRT method is not yet generated, so legacy interrupt routing
doesn't work for devices with multiple functions.
Tested on an ASRock H81M-HDS. Using a Radeon HD 6450 graphics card works
under GNU/Linux, with PRIME [1]. An x1 PCIe card was also tested in the
PEG slot, and it appears functional.

The existing code sets DEVEN with the intention of enabling the IGD and
Mini-HD audio. However, according to the datasheet [1] and some testing
on hardware, the bits in DEVEN are set by default if and only if the
straps/fuses say the device should be enabled. To illustrate this, here
are a few initial values of DEVEN on some Haswell systems:
Supermicro X10SLM+-F: 0x0000002d
ASRock H81M-HDS: 0x00000039
Acer C720: 0x000000b1
On the X10SLM+-F, the IGD is disabled by default, and PEG10 & PEG11
are enabled by default. On the C720, the PEG devices are all disabled
by default, while the IGD and Mini-HD audio are already enabled.
There are two issues that result from the existing behaviour: PEG
devices are unconditionally disabled, and devices are set as enabled
when it's not actually possible to enable them.
So, don't touch the DEVEN register at this stage, as there are no
benefits.
Interestingly, on an Acer C720 (Google Peppy), a PCI device 00:04.0
appears. It is a thermal sensor. `powerstat` was used to measure idle
power usage over 30 minutes under Debian GNU/Linux 9.6. There was no
change in reported power draw.

This allows devices to be properly disabled when they are set to `off`
in the devicetree, or when a device has its `enabled` property set to
false.
A message is printed stating that a device is being disabled, even if
it was already disabled via DEVEN. However, it could be useful to have
this information, so such messages are kept.
The device 00:04.0 is a thermal sensor on the Acer C720, but it has not
been named as such in this patch. This is because the public datasheets
never formally acknowledge what the device is, and how it might differ
across platforms.
Tested on a Supermicro X10SLM+-F. The Mini-HD audio is disabled now,
silencing a warning from Linux.
Also tested on an Acer C720 (Google Peppy). Disabling "device 4" from

Also tested on an ASRock H81M-HDS. For this device, and all other test

This bug/typo was spoted by Felix Held.
As documented in the datasheet, to enable PMEGPE, HPGPE, GENGPE, we need
to write 0x7 into DEV(0:01.0) register "PCI Express-G Legacy Control"
located at 0xec.
Used address at 0x114 to enable GPEs is likely a typo.
Patch not tested.

* Remove FSP Sandy/Ivybrige which are unused.
* Open Source implementation isn't final but
good enough to replace FSP version.
* For new ports use NORTHBRIDGE_INTEL_IVYBRIDGE
and NORTHBRIDGE_INTEL_SANDYBRIDGE

On an ASRock H81M-HDS neither libgfxinit, nor Linux, is able to
initialise the display when lanes are not configured to be shared
between DDI A and DDI E.
Intel's reference manual [1] states that the decision to share lanes
between DDI A and DDI E is "based on board configuration". Hence, add a
new field to the devicetree that boards can set. All existing Haswell
boards have this unset, thus taking a value of 0, so there is no change
to existing behaviour.

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
payloads (e.g. tianocore) even bail out on this. To overcome this issue mark the
region between tom and cbmem as uma.
