By not defining CONFIG_SYS_PCI_MASTER_INIT and CONFIG_SYS_PCI_TARGET_INIT, PCI support (host and adapter) will not be enabled. But it's still possible to use the U-Boot PCI infrastructure for the PCIe ports.

This configuration option is needed for a new 460GT board, which uses PCIe but has PCI disabled.
