2021-03-07sb/intel/common/pciehp: Replace HP dummy device with common codeArthur Heymans
Use the common PCIEXP_HOTPLUG code to generate a dummy device for PCIe ports supporting hotplug. This allows to have control over how much resources are allocated to hotplug ports. Tested on thinkpad X220: now hotplugging a dGPU via the expresscard slot sometimes works.

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.

2020-06-10sb/intel/bd82x6x/pcie.c: Move `pch_pcie_acpi_name` upAngel Pons
The ASSERT() macro depends on the line number, so changing the line it appears in breaks reproducibility testing using BUILD_TIMELESS=1. Work around this problem by placing the `pch_pcie_acpi_name` function, which contains this macro, at the beginning of the file. This allows refactoring the rest of the code without affecting the ASSERT() macro.

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.

2012-05-01Fix issue with PCIe power management setupDuncan Laurie
The current early PM setup that attempts to configure dynamic clock gating relies on PCIe functions to be enabled that may not be. Instead of reading port 0 or 4 directly to determine the link width use the register that refelects the soft strapping options as this will always be available. Also add a clear register assignment and break for port 0 in the switch statement instead of falling through to port 4 as that could end up setting the slot power limit based on port 4 values instead of based on port 0. register 0xE1=0x3f and all other root ports should have 0xE1=0x03. When port 0 and 4 are disabled they will have 0xE1=0x3C before being disabled by the pch enable handler.
