The alignment is relevant to determine whether this is part of a larger 
IP block or not, though I am not sure why you use 64KB as a criteria. 
Our HW rules are to match the highest OS available page size for the 
systems, for us it used to be 4KB and is now 16KB alignment.

The block is part of a "sundry" IP which has lots of controls that did 
not belong anywhere else, for better or for worse (pin/mux controls, SoC 
identification, drive strength, reset controls, and other misc bits).
