Some book3s (e300 family for instance, I think G2 as well) already have

The original "G2" (meaning 603 and 604) do not have DABR2. The newer
"G2" (meaning e300) does have it. e500 and e600 do not have it either.
Hope I got that right ;-)
G2 core reference manual says:
Features specific to the G2 core not present on the original MPC603e
(PID6-603e) processors follow:
...
Enhanced debug features
— Addition of three breakpoint registers—IABR2, DABR, and DABR2
— Two new breakpoint control registers—DBCR and IBCR
e500 has DAC1 and DAC2 instead for breakpoints iaw e500 core reference
