Allow selecting either SATA or PCIE functionality using uImage.FIT configurations and device-tree overlays. By default, PCIE1 is selected (as it has been before this change). To select SATA instead, you can do this now: fw_setenv bootconf config-mt7622-bananapi-bpi-r64-sata and reboot. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
