4e8bbc11d0 include/device/azalia_device.h: Merge location1 and location2
This changes the location to be expressed as a combination of ORs. This
allows aliases for special locations.

For example, `AZALIA_REAR_PANEL` is easier to read than
`AZALIA_EXTERNAL_PRIMARY_CHASSIS, AZALIA_SPECIAL7`.

4a62b8a599 include/device: Merge enums from azalia_device.h and azalia.h
We were keeping 2 copies of the same thing (albeit there were some
slight differences). As azalia_device.h is used much more in the
codebase this was kept as the base and then some of the nice features
of azalia.h were incorporated.

The significant changes are:
 - All enum names now use the `AZALIA_` prefix.

This also drops the AzaliaPinConfiguration enum as it was never used
since added in 2013.

545c532902 mb/siemens/mc_ehl3: Use PSE GbE 0 instead of PSE GbE 1
As a result of hardware changes on this board, the PHY previously
routed to the PSE GbE 1 is now routed to PSE GbE 0 on the Elkhart Lake
SoC.

This patch changes the device PCI ID in the board's devicetree and
accordingly, the GPIO configuration.

BUG=none
TEST=Boot into Linux and observe whether both PSE GbE 0 and PCH GbE
are working, while PSE GbE 1 remains inactive (not listed by 'ip link')
.

0458a4428d mb/siemens/mc_ehl5: Set LVDS re-power delay to 1 s

The .inc suffix is confusing to various tools as it's not specific to

This issue is also seen in the release notes generation script where
Makefiles get renamed before running cloc.

722c0b7b21 mb/siemens/mc_ehl: Enable write access for SPD EEPROM on mc_ehl1
The address space of possible SPD-EEPROMs 0x50..0x53 on the SMBus
interface is per default write-protected in FSP. This avoids that an
SPD-EEPROM on a DRAM module gets overwritten by the host.

On mc_ehl1, memory-down configuration is used and there is no SPD EEPROM
available. Nevertheless, there is a general purpose EEPROM on the same
address available which needs to stay writeable.

This patch disables the default-enabled write protect feature for the
SPD-EEPROM addresses just for mc_ehl1.

Test=Boot into Linux and make sure a write access into the EEPROM is
possible.

a52d38b637 mb/siemens/mc_apl2: 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
Reset Control Register") explained.

Any file in the coreboot project without a specific license is bound
to the license of the overall coreboot project, GPL Version 2.

makefiles in the mainboard directory that don't already have an SPDX

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
Reset Control Register") explained.
