This adds a new port for the ASRock H77 Pro4-M motherboard. It is
microATX-sized with an LGA1155 socket and four DIMM sockets for DDR3
SDRAM.
The port was initially done with autoport. It is quite similar to the
ASRock B75 Pro3-M which is already supported by coreboot.
Working:
- Sandy Bridge and Ivy Bridge CPUs (tested: i5-2500, Pentium G2120)
- Native RAM initialization with four DIMMs of two different types
- PS/2 combined port (mouse or keyboard)
- Integrated GPU by libgfxinit on all monitor ports (DVI-D, HDMI, D-Sub)
- PCIe graphics in the PEG slot
- All three additional PCIe slots
- All rear and internal USB2 ports
- All rear and internal USB3 ports with reasonable transfer rates
- All six SATA ports from the PCH (two 6 Gb/s, four 3 Gb/s)
- All two SATA ports from the ASM1061 PCIe-to-SATA bridge (6 Gb/s)
- Rear eSATA connector (multiplexed with one ASM1061 port)
- Console output on the serial port of the Super I/O
- SeaBIOS 1.15.0 to boot slackware64
- SeaBIOS 1.15.0 to boot Windows 10 (needs VGA BIOS)
- Internal flashing with flashrom-1.2 (needs `--ifd -i bios --noverify-all`)
- External flashing with flashrom-1.2 and a Raspberry Pi 1
- S3 suspend/resume from either Linux or Windows 10
Not working:
- Booting from the two SATA ports provided by the ASM1061
- Automatic fan control with the NCT6776D Super I/O
Untested:
- VBT (it is included, though)
- Infrared header

Currently, the pmc_mux/conn driver uses integer fields to store the
USB-2 and USB-3 port numbers from the SoC's point of view. Specifying
these as integers in the devicetree is error-prone, and this
information can instead be represented using pointers to the USB-2 and
USB-3 devices. The port numbers can then be obtained from the paths of
the linked devices, i.e. dev->path.usb.port_id.
Modify the driver to store device pointers instead of integer port
numbers, and update all devicetrees using the driver. These are the
mainboards affected (all are Intel TGL or ADL based):
google/brya

According to util/kbc1126/README.md, for these ECs to work, the
address and size of their two firmware should be written to $s-0x100`
(`$s` means the image size, done with kbc1126_ec_insert), which means
that every existing section (especially those used to store code)
should not overlap this address, otherwise the bootblock will get
damaged when inserting firmwares of the EC.
In this commit, ecfw_ptr is a structure initialized at build time
according to CONFIG_KBC1126_FW1_OFFSET and CONFIG_KBC1126_FW2_OFFSET
(to do so, they should be redefined as hex), and linked to
CONFIG_ECFW_PTR_ADDR within bootblock, so kbc1126_ec_insert is not

device. This can cause i2c devices to malfunction or cause timing
sequence violations if:
1) ACPI exports a PowerResource for the device that uses GPIOs that are
also exported in _CRS
2) The kernel driver for the device uses the GPIOs exported in _CRS for
its own purposes. This means the state of the pin is out of sync
between platform firmware and the kernel. The Linux ELAN I2C
touchcsreen driver (https://source.chromium.org/chromiumos/chromiumos/codesearch/+/main:src/third_party/kernel/upstream/drivers/input/touchscreen/elants_i2c.c;l=1429)
is one example of this.
Therefore, add disable_gpio_export_in_crs to all brya variants that use
the drivers/i2c/generic or drivers/i2c/hid chip drivers.
