Easy Way to Read UID(Unique ID) on i.MX53

Greetings,

 

I',m working on a i.MX53-based board, running linux(BSP 11.09). Lately, I'm with the requirement of obtain an identificator that must be unique to every board. I've been searching, and I notice the IIM module on Reference Manual, that claims to have a UID(Unique ID) information, but I can't figure out how to obtain it. I've tried to use this kernel module(mxc_iim), but it don't seems to access the UID information. Apparently, this module only access the IIM's Control Registers. Anybody could help me telling me an easy way to access this UID?

 

Thanks in advance

Ricardo Gurgel.
