2020-07-30	soc/amd/picasso: Split ops for internal and external PCIe GPP bridges	Furquan Shaikh
	This change splits the device operations for internal and external PCIe GPP bridges so that the external bridges use `pciexp_scan_bridge()` instead of `pci_scan_bridge()`. `pciexp_scan_bridge()` is required for external GPP bridges to enable ASPM on downstream devices if supported.

2020-07-10	soc/amd/picasso: Add driver for handling PCIE GPP bridges	Furquan Shaikh
	This change adds a driver pcie_gpp.c which provides device_operations for external and internal PCIe GPP bridges. These device operations include standard PCI bridge operations as well as operations for generating ACPI node for the device and returning appropriate ACPI name for it.
