GPIO APU_BIOS_FLASH_WP_L is first read in ROM stage to determine the
state of the BIOS FLASH Write Protect signal at boot.
The result of this read accumulated in the vboot state that's passed on
to the upper layers of the stack.
Therefore this GPIO must be configured as a "reset stage" GPIO, not
a "RAM" stage GPIO.

In early stages (pre ramstage), we have two notions of devices.
To access the hardware, "simple device" handles are used. These
are plain numbers. To access the static information of the device
tree, we use `struct device` pointers. This is referred to as
DEVTREE_EARLY in the code.
This file is about the latter and its name reflects that the
tree remains unmodified.

Add new port based on autoport.
The board uses a NPCD378 SuperIO, that is full of custom hardware.
The 8MiB flash SOIC-8 can be accessed after cutting of a part of the
DIMM slot holder. The flash IC has no diode, powering a part of the
board while flashing externaly, including the Standby-LED.
The following have been tested and is working:
* Native raminit with up to four DIMMs
* Libgfxinit on DisplayPort
* USB
* EHCI debug
* Serial on RS232
* Ethernet
* PCIe on x4
* PCIe on x16
* SATA
* Booting GNU Linux 4.14 using SeaBIOS 1.11.1 as payload
* Flashing internaly
* PS/2 is working
Untested:
* PCI slot
* LPT port
* VBIOS
* S3 resume
Not working:
* PSU fan managment (runs at 100%)
* Half of SuperIO functionality is unknown
TODO:
* Reverse engineer remaining SuperIO registers
* Reverse engineer SMM
Fixes on follow-up commits:
* Added PSU fan control
* Reverse engineered some of Super IO's HWM registers
* Added SMBIOS tables for IPMI

Tested with GRUB 2.02 as a payload, booting Arch Linux with
latest kernel. This code is based on the output of autoport
as well as existing ga-b75m-d3h and ga-b75m-d3v mainboards.
Working:
- Serial port I/O
- S3 suspend/resume (broken with SeaBIOS 1.11.1)
- USB ports and headers
- Gigabit Ethernet
- Integrated graphics (libgfxinit)
- PCIe x16 graphics
- PCIe x1
- SATA controller
- Hardware Monitor
- Fan Control (fancontrol on linux works well)
- Native raminit (4+4GB, 4+2GB, 2+2GB, DDR3-1333)
- Native graphics init with libgfxinit
- flashrom, using the internal programmer. Tested with coreboot,
as well as with the vendor firmware. Backup chip is untested.
- NVRAM settings. Only `gfx_uma_size` and `debug_level` have been
tested with values different from the default.
Untested:
- VGA BIOS for integrated graphics init
- DVI port. It can detect a "fake" display, that is, an
EEPROM connected to the DVI port.
- PS/2 ports
- Audio: Only rear output (green) has been tested.
- EHCI debug.
- Parallel port
- Non-Linux OSes
- ACPI thermal zone and fan control (probably not working)
Not working:
- SATA devices with Tianocore (payload issue)
- PCIe to PCI bridge. It seems to be poorly supported on Linux,
it lacks a public datasheet and vendor BIOS behaves in the
same way: The bridge and the devices behind it appear, but
drivers fail to find devices attached to the bridge.

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.
