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.

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.

Looks like no one really knows what this bit would be useful for, nor when it would need to be set. Especially if coreboot is setting it even on PCI *Express* bridges. Digging through git history, nearly all instances of setting it on PCIe bridges comes from i82801gx, for which no reason was given as to why this would be needed. 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 negation in the name could trick people into setting this bit again. Tested on Asrock B85M Pro4, no visible difference.

The only user of the `pch_silicon_type` function is the `pch_is_lp` function so replace the former with the new `get_pch_platform_type` function.

Advertising SMI triggers in FADT is only valid if we exit with SMI installed. There has been some experiments to delay SMM installation to OS, yet there are new platforms that allow some configuration access only to be done inside SMM. Splitting static HAVE_SMI_HANDLER variable helps to manage cases where SMM might be both installed and cleared prior to entering payload.

2020-05-02acpi: Move ACPI table support out of arch/x86 (3/5)Furquan Shaikh
This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 3/5 which basically is generated by running the following command: $ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g' BUG=b:155428745 Change-Id: I16b1c45d954d6440fb9db1d3710063a47b582eae Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40938 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>
