Hi there I disabled CONFIG_DM_PCI in menuconfig because I have problem detecting AHCI SCSI controller on X86 board with CONFIG_DM_PCI enabled and the older code in drivers/pci/pci.c works for me in the previous U-boot version.

It seems that the code refers to the DM_PCI code regardless if CONFIG_DM_PCI is enabled or not. Is it ok to build U-boot with CONFIG_DM_PCI disabled or did I miss anything?
x86 has been fully converted to DM PCI, so legacy PCI driver is not supported now.
Which board are you using? Can you debug why AHCI does not work with DM PCI?
