Only one of two PCIe host controllers are recognized #47
Description
There are two PCIe host controllers (pcie0: pcie@2B000000, pcie1: pcie@2C000000), but only second one is intialized by U-Boot. First PCIe host controller contains XHCI (USB 3) that is required for booting from USB mass storage devices. It is also needed for operating systems that assume that PCI is already initialized by boot loader.
pcie0 seems disabled in FDT config (status = "disabled"), but attempting to enable it manually cause only first PCIe host controller to be properly initalized.
