You can use UUID to specify the partitions unique ID number, you can name the partitions, this is the default and you can get a race condition if 2 partitions are named the same thing, so yes it does scan through everything.
Ok, what do i need to edit or what command to send to choose a specific uuid and set it permanently? or its not needed if there are no other drive with valid info to boot from? lets say i only have those 2 mentioned hdd, one with a bootable image and the other without, uboot is smart enough to not give errors and use the one actually bootable on every try?
