8ebd8cc348 mainboard: Add SPDX license headers to Makefiles
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.

b6940dfdae mb/siemens/mc_ehl4: Change GPIO GPP_B5 polarity for DRAM population
With the latest hardware revision, the polarity of GPP_B5 has been
changed. For a full-populated DRAM configuration, the input signal is
now connected to 3.3 V and for a half-populated configuration it is
connected to ground.

BUG=none
TEST=Use different populated mainboards and check coreboot log

GPP_B5 = 0:
[INFO ]  meminit_channels: DRAM half-populated
[DEBUG]  1 DIMMs found

81fb981e8e mb/siemens/mc_ehl: Make DRAM population configurable
There can be mainboard variants, which are only equipped with
half-populated DRAM. For this reason, the meminit parameter for
populatation should be adjustable. The default setting remains at
full-populated DRAM. At mainboard variant level a different selection
via individual input paths can be made.

7ad8b0987a mb/siemens/mc_apl5: Set Full Reset Bit into Reset Control Register
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 04ea73ee78 ("siemens/mc_apl3: Set Full Reset Bit into

14701a4df3 soc/intel/elkhartlake: Define DIMM_SPD_SIZE in SoC Kconfig
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.
