2020-11-20soc/intel/common: Add PCIe Runtime D3 driver for ACPIDuncan Laurie
This driver is for devices attached to a PCIe root port that support Runtime D3. It creates the necessary PowerResource in the root port to provide _ON/_OFF methods for which will turn off power and clocks to the device when it is in the D3cold state. The mainboard declares the driver in devicetree and provides the GPIOs that control power/reset for the device attached to the root port and the SRCCLK pin used for the PMC IPC mailbox to enable/disable the clock. An additional device property is created for storage devices if it matches the PCI storage class which is used to indicate that the storage device should use D3 for power savings. BUG=b:160996445 TEST=boot on volteer device with this driver enabled in the devicetree and disassemble the SSDT to ensure this code exists.

2020-07-28src: Never set ISA Enable on PCI bridgesAngel Pons
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.

2020-07-12soc/intel/common/block/pcie: Select ASPM on mainboard basisChristian Walter
Current the common soc code automatically selects PCIEXP_CLK_PM and PCIEXP_L1_SUB_STATE which breaks booting Windows with a PCIE NVIDIA graphics card attached on mainboards that do not have a CLKREQ# signal. This is commonly used on server and workstations boards where the additional power savings of L1 substate are not required. Make the PCIEXP_CLK_PM and PCIEXP_L1_SUB_STATE default y but do not select it anymore by the soc code, thus we can disable it in the mainboard code. Tested on CFL with Windows 10.

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.

2019-11-16soc/intel: Implement PCIe RP devicetree update based on LCAPNico Huber
Most of the current implementations for FSP-based platforms make (sometimes wrong) assumptions how FSP reorders root ports and what is specified in the devicetree. We don't have to make assumptions though, and can read the root-port number from the PCIe link capapilities (LCAP) instead. This is also what we do in ASL code for years already. This new implementation acts solely on information read from the PCI config space. In a first round, we scan all possible DEVFNs and store which root port has that DEVFN now. Then, we walk through the devicetree that still only knows devices that were originally mentioned in `devicetree.cb`, update device paths and unlink vanished devices. To be most compatible, we work with the following constraints: o Use only standard PCI config registers. o Most notable, don't try to read the registers that configure the function numbers. FSP has undocumented ways to block access to non-standard registers. o Don't make assumptions what function is assigned to hidden devices. The following assumptions were made, though: o The absolute root-port numbering as documented in datasheets matches what is read from LCAP. o This numbering doesn't contain any gaps. o Original root-port function numbers below a PCI device start at function zero and also don't contain any gaps.
