The connected panel on this mainboard gets the PWM frequency directly
from the Elkhart Lake CPU. The PWM controls the brightness of the
backlight. Therefore, it is necessary to activate the PWM passthrough
mode in the PTN3460 eDP-to-LVDS bridge (see PTN3460 Programming Guide -
5. Configuration Registers).

With the introduction of a new Linux version a problem has appeared
after a software initiated reset via CF9h register. The problem
manifests itself in the fact that the Linux kernel does not start after

To help identify the licenses of the various files contained in the
coreboot source, we've added SPDX headers to the top of all of the
.c and .h files. This extends that practice to Makefiles.
Any file in the coreboot project without a specific license is bound
to the license of the overall coreboot project, GPL Version 2.
This patch adds the GPL V2 license identifier to the top of all
makefiles in the mainboard directory that don't already have an SPDX

The default SPD size is set to 256 bytes, instead of 512 for
LPDDR4/DDR4 if not overridden by the mainboard Kconfig. This caused
the SMBus libraries to read only the lower half of the DIMM SPD on
protectli/vault_ehl. The lower half of the SPD passed to FSP causes
a bug in DIMM change detection, which relies on the CRC of the
manufacturer bytes in the upper half of the SPD (CRC of zero bytes
always gives zero so no change was assumed). Setting the DIMM SPD size
to 512 fixes it.
Setting the SPD size in SoC will also avoid such problems in the future
Elkhart Lake ports. Elkhart Lake supports only LPDDR4/DDR4 so providing
the correct default of 512 bytes is an obvious thing to do.
TEST=Boot Protectli VP2420 (vault_ehl) with different DIMMs and see
FSP is retraining the memory instead of doing the fastboot with old
DIMM data.

As for mainboard mc_ehl1, a hard real-time dependency is also required
for this mainboard. The L1 prefetcher on Elkhart Lake is too aggressive
which in the end leads to an increased number of cache misses. Disabling
the L1 prefetcher boosts up the performance (in some cases by more than
10 %) in this specific use case.

This mainboard has three Marvel PHYs connected to the internal SOC GbE
controllers. The default LED status after HW reset of this PHYs shows a
different mode than what is needed. LED[2] is not connected on this
mainboard.
This patch sets the following LED status:
LED[0] - 7 = On - 1000 Mbps Link, Off - Else
LED[1] - 1 = On - Link, Blink - Activity, Off - No Link
LED[2] - not connected
TEST=Try different register values to verify LED feature.

Instead of creating a dummy I2C device in order to force Linux to
decrease the I2C bus speed, use the own 'bus_speed' field of RV3028
device config structure.
Linux should always set the bus speed to the speed of the slowest
device sitting on the bus. Hence the dummy device is not needed
here anymore.
BUG=none
TEST=See if the RV3028 RTC is visible and working (date/time can
be set/read) in Linux. At the time, a driver modification is needed
to add a match table for the "MCRY3028" ACPI HID. A proper kernel
patch is pending.

In Linux, the I2C speed defaults to 400 kHz if there is no device
registered in ACPI which requests a different speed. Due to board
limitations (layout, bus load), 400 kHz are too fast which results in a
timing violation. Therefore, add a dummy I2C device to both used I2C
buses (I2C1 and I2C2) with a speed of 100 kHz. This will limit the bus
speed in Linux accordingly.

Apollo Lake seems to start with PCIe root ports unusable/uninitialized
before FspMemoryInit() is called and FSP-M properly initializes these
root ports.
However, we need the root ports accessible before FspMemoryInit() in
certain cases, such as emitting POST codes through a PCIe device.
For the initialization to happen properly, certain register writes
specified in Apollo Lake IAFW BIOS spec, vol. 2 (#559811), chapter
3.3.1 have to be done.
BUG=none
TEST=Boot on siemens/mc_apl2 with NC_FPGA_POST_CODE enabled and check
that the POST codes are emitted before FspMemoryInit().

of the old RX6110SA the new Micro Crystal RTC RV3028 is used now. Since
the address of this new RTC conflicts with an EEPROM on I2C bus 2, the
