Heinrich Schuchardt 8cf8ad3533 efi_driver: don't bind internal block devices ... UEFI block devices can either mirror U-Boot's internal devices or be provided by an EFI application like iPXE. When ConnectController() is invoked for the EFI_BLOCK_IO_PROTOCOL interface for such an application provided device we create a virtual U-Boot block device of type "efi_blk". Currently we do not call ConnectController() when handles for U-Boot's internal block devices are created. If an EFI application calls ConnectController() for a handle relating to an internal block device, we erroneously create an extra "efi_blk" block device. E.g. the UEFI shell has a command 'connect -r' which calls ConnectController() for all handles with device path protocol. In the Supported() method of our EFI_DRIVER_BINDING_PROTOCOL return EFI_UNSUPPORTED when dealing with an U-Boot internal device.
