Could you please point to any examples? Also, the pci_find_and_bind_driver function only checks for this flag in the drivers when binding the devices See host-bridge@0,0 in chromebook_coral.dts for an example of using the u-boot,dm-pre-reloc flag. Note that pci_find_and_bind_driver() is only called if the device tree lacks anything. Which board is this for? Regards, Simon
