The unit addresses need to match "reg".
[SL] You mean  "@1" should match to "reg = <2 3>" ?
As each e6500 core in B4860 is dual- threaded, reg property here represents the thread's identifier in that PA core.

So convention used in T4 and B4 is: core 0 having threads 0 and 1,
						Core 1 having <2 3> and so on....
