Output like the following is quite irritating:

=> bootefi hello Scanning disk mmc2.blk... No valid Btrfs found Bad magic number for SquashFS image. ** Unrecognized filesystem type ** Scanning disk mmc1.blk... No valid Btrfs found Bad magic number for SquashFS image. ** Unrecognized filesystem type ** Scanning disk mmc0.blk... No valid Btrfs found Bad magic number for SquashFS image. ** Unrecognized filesystem type **

It is expected that most partitions don't contain a Btrfs. This is only worth a debug message.
