'loop' is not a filesystem, it is a block device. But, I'm not sure the data being displayed is a filesystem. If I had to guess, based on the evidence: an mtd image, and the existence of what seems to be boot parameters, I'd say that it is a bootloader, such as U-Boot. As such, there is no unpacking to be done on it.
Perhaps if you can describe more about its origin, a better answer can be given. In general, one cannot determine much from a small sample of data, and without some context regarding the origin of the data.
