When comparing hex dumps it is useful to see the offsets of the registers. Add them in where they correspond to a multiple of 16.
Possibly it would be useful to have a a command to output the FSP values in human-readable form, making use of the fsp_bindings implementation.

So this is a hex number, please make it explicit by adding the 0x prefix to all these numbers otherwise it's quite confusing.
