2020-10-24sb/intel/lynxpoint/pcie: Fix clock gating routineAngel Pons

2020-10-12sb/intel/lynxpoint: Enable/disable AER via KconfigMatt DeVillier
Several changes[1][2] to the Linux kernel now enable ASPM/AER for the rt8169 network driver, for which it was previously disabled. This, coupled with the southbridge enabling AER for all PCIe devices, has resulted in a large amount of AER timeout errors in the kernel log for boards which utilize the rt8169 for on-board Ethernet (e.g., google/beltino). While performance is not impacted, the errors do accumulate. To mitigate this, guard AER enablement via Kconfig, select it by default (as to maintain current default behavior), and allow boards which need to disable it to do so (implemented in subsequent commits). This implementation is derived from that in soc/intel/broadwell. Test: build/boot google/beltino variants with AER disabled (CB:46136), verify dmesg log free of AER timeout errors.

Both PCH types are very different, and mixing the code for both together isn't useful. First of all, inline `pch_is_lp` to return a constant. This allows the compiler to optimize out unused code, which results in smaller executables. For the Asrock B85M Pro4, it's about 2.5 KiB less. Subsequent commits will further split the southbridge code.

2020-08-29sb/intel/bd82x6x: Factor out common ME functionsAngel Pons
We can now factor out the essentially duplicated ME functions. We include a .c file to preserve reproducibility. This is needed because there are two different `mei_base_address` global variables, and we have to access the same variables in order for builds to be reproducible. The duplicate global in `me.c` and `me_8.x.c` will be completely gone once this new `me_common.c` file becomes a standalone compilation unit. We are wrapping some things in static inline functions, as they won't be directly accessible anymore after moving to a separate compilation unit. Tested with BUILD_TIMELESS=1, Asus P8Z77-V LX2 remains identical.

2020-08-07sb/intel/lynxpoint: Consider root ports being disabled by strapAngel Pons
PCIe RPC (Root Port Configuration) straps will force-disable some root port functions if some root ports have a width greater than x1. In two cases, this affects the last function. The PCIe init code will never finish configuring the root ports if that is the case: it assumes that the last function will eventually run through the code, but it doesn't. If PCIe initialization does not complete, pressing the power button will not power off the board, unless it is held for about five seconds. Also, Windows 10 will show a BSOD about MACHINE CHECK EXCEPTION, and lock up instead of rebooting. Depending on the microcode version, the BSOD may not be visible. This happens even when the root port is not populated. Use the strap fuse configuration value to know which configuration the PCH is strapped to. If needed, update the number of ports accordingly. In addition, print the updated value to ease debugging PCIe init code. Existing code in coreboot disagrees with public documentation about the root port width straps. Assume existing code is correct and document these assumptions in a table, as an explanation for the added code. Tested on Asrock B85M Pro4, PCIe initialization completes successfully.

The other instances in Intel code seem to have been, unsurprisingly, copy-pasted. Drop all uses of this definition and rename it to avoid confusion.

The early SMBus code for this southbridge checked if the PCI device ID is valid. However, we can't easily do that in common code, and we should not attempt to do so either: if a SMBus device behaves differently, then it should not be using the common code anyway.

According to the ACPI specification, version 6.3: Accesses to the PM1 status registers are done through byte or word accesses. The same is said about the PM1 Enable registers. Therefore, reporting dword-sized access is wrong and means nothing anyway. Since some other platforms use word-sized access, use word everywhere for consistency.

2020-07-20src: Make HAVE_CF9_RESET set the FADT reset registerAngel Pons
All supported x86 chips select HAVE_CF9_RESET, and also use 0xcf9 as reset register in FADT. How unsurprising. We might as well use that information to automatically fill in the FADT accordingly. So, do it. To avoid having x86-specific code under arch-agnostic `acpi/`, create a new optional `arch_fill_fadt` function, and override it for x86 systems.
