This\nbroke basically all AMD platforms, since they have a lot of internal SOC\ndevices behind these functions.\n\nThis was detected, because the XHCI controller and therefore the USB\ndevices were not found by u-boot on AMD/crater platform.\n\nPCI_MASK_BUS() returns both device and function bits, so it skipps any\nbdf where either device > 0 or function > 0. Using PCI_DEV() extracts\nonly the device number, matching the intent in only_one_child().\nIt therefore now checks all functions on device 0 (Linux does the same).\n\nI build tested u-boot as coreboot payload and run it on a recent x86 AMD\nplatform. Devices like the XHCI controller are now found again.\n\nFixes: fbde868ba4aa (\"pci: skip unnecessary PCIe scanning\")\nSigned-off-by: Maximilian Brune <maximilian.brune@9elements.com>\nCC: Tom Rini <trini@konsulko.com>\nCC: Andrew Goodbody <andrew.goodbody@linaro.org>\nCC: George McCollister <george.mccollister@konsulko.com>\nCC: Simon Glass <sjg@chromium.org>\n---\n drivers/pci/pci-uclass.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)", "diff": "diff --git a/drivers/pci/pci-uclass.c b/drivers/pci/pci-uclass.c\nindex 83b76d01f24..f58d542ef75 100644\n--- a/drivers/pci/pci-uclass.c\n+++ b/drivers/pci/pci-uclass.c\n@@ -927,7 +927,7 @@ int pci_bind_bus_devices(struct udevice *bus)\n \t\tif (PCI_FUNC(bdf) && !found_multi)\n \t\t\tcontinue;\n \n-\t\tif (only_one_child(bus) && (PCI_MASK_BUS(bdf) > 0))\n+\t\tif (only_one_child(bus) && (PCI_DEV(bdf) > 0))\n \t\t\tcontinue;\n \n \t\t/* Check only the first access, we don't expect problems */\n", "prefixes": [ "v2" ] }
