2021-01-01nb/intel/hsw,soc/intel/{bdw,skl,apl},mb/*: unify dt panel settingsMichael Niewöhner
There are multiple different devicetree setting formats for graphics panel settings present in coreboot. Replace the ones for the platforms that already have (mostly) unified gma/graphics setup code by a unified struct in the gma driver. Hook it up in HSW, BDW, SKL, and APL and adapt the devicetrees accordingly. Always ensure that values don't overflow by applying appropriate masks. The remaining platforms implementing panel settings (GM45, i945, ILK and SNB) can be migrated later after unifying their gma/graphics setup code.

2020-05-04soc/intel/skl: always enable SataPwrOptEnableMichael Niewöhner
For unknown reasons FSP skips a whole bunch of SIR (SATA Initialization Registers) when SataPwrOptEnable=0, which currently is the default in coreboot and FSP. Even if FSP's default was 1, coreboot would reset it. This can lead to all sorts of problems and errors, for example: - links get lost - only 1.5 or 3 Gbps instead of 6 Gbps - "unaligned write" errors in Linux - ... At least on two boards (supermicro/x11-lga1151-series/x11ssm-f and purism/librem13v2) SATA is not working correctly and showing such symptoms. To let FSP correctly initialize the SATA controller, enable the option SataPwrOptEnable statically. There is no valid reason to disable it, which might break SATA, anyway. Currently, there are no reported issues on CML and CNL, so a change there could not be tested reliably. SKL/KBL was tested successfully without any noticable downsides. Thus, only SKL gets changed for now.

They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

The devicetree is not made for user-choosable options, thus introduce Kconfig options for both SGX and the corresponding PRMRR size. The PRMRR size Kconfig has been implemented as a maximum value. At runtime the final PRMRR size gets selected by checking the supported values in MSR_PRMRR_VALID_CONFIG and trying to select the value nearest to the chosen one. When "Maximum" is chosen, the highest possibly value from the MSR gets used. When a too strict limit is set, coreboot will die, printing an error message.

2017-09-21soc/intel/skylake: Add config for enabling LTR for PCIe Root portRizwan Qureshi
There are a lot errors reported by AER driver for root port 0. The erors are being caused by an unsupported request from the device to the upstream port. Enabling LTR on the root port stops these errors, it is because LTR is enabled on the device side but not on the root port and hence root port was logging the LTR messages from the device as unsupported. The PCIe base spec (v3.1a) section 6.18 also states that: LTR support is discovered and enabled through reporting and control registers described in Chapter 7. Software must not enable LTR in an Endpoint unless the Root Complex and all intermediate Switches indicate support for LTR. Note that it is not required that all Endpoints support LTR to permit enabling LTR in those Endpoints that do support it. When enabling the LTR mechanism in a hierarchy, devices closest to the Root Port must be enabled first. If an LTR Message is received at a Downstream Port that does not support LTR or if LTR is not enabled, the Message must be treated as an Unsupported Request. FSP has a UPD for enabling/disabling LTR on root port, use the same for configuring LTR on PCIe root ports.
