If there is no pci device listed in the device tree, don't bother scanning the device tree.
Signed-off-by: Bin Meng <[email protected]> --- Simon, I see the following v2 patches were applied, but don't see you replied the patch thread to mention it's been applied. - x86: fsp: Call fsp_init_phase_pci() in pci_uclass_post_probe() - fdtdec: Fix possible infinite loop in fdtdec_get_pci_vendev() - dm: pci: Save devfn without bus number in pci_uclass_child_post_bind() I assume these patches look good, so I don't include those patches in the v3 series. Let me know if there is any issue. Changes in v3 respin: - Fix typo of 'tree' Changes in v3: - Rebase on u-boot-x86/master - Drop v2 patches which were already applied drivers/pci/pci-uclass.c | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/drivers/pci/pci-uclass.c b/drivers/pci/pci-uclass.c index 2d12344..b25298f 100644 --- a/drivers/pci/pci-uclass.c +++ b/drivers/pci/pci-uclass.c @@ -632,6 +632,13 @@ error: static int pci_uclass_post_bind(struct udevice *bus) { /* + * If there is no pci device listed in the device tree, + * don't bother scanning the device tree. + */ + if (bus->of_offset == -1) + return 0; + + /* * Scan the device tree for devices.
