2023-08-06mainboard: Add SPDX license headers to MakefilesMartin Roth
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 license line at the top.

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 the reboot. The problem is solved by setting bit 3 to 1 in Reset Control Register (I/O port CF9h). This leads to the fact that the PCH will drive SLP_S3 active low in the reset sequence. It leads to the same behavior as in commit 04ea73ee78bc ("siemens/mc_apl3: Set Full Reset Bit into Reset Control Register") explained.

2023-03-23soc/intel/elkhartlake: Define DIMM_SPD_SIZE in SoC KconfigMichał Żygowski
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.

2022-11-18mb/siemens/mc_ehl2/devicetree.cb: Use RV3028 bus_speed instead of dummy i2c ↵Jan Samek
device 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.

2022-11-09mb/siemens/mc_ehl2: Add dummy I2C devices to limit the I2C speed in OSWerner Zeh
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.
