Actually, I am also puzzled by this issue. We used 
another JTAG tool on MPC7447A debug and had the 
similar issue. Recently, we used BDI2000 on a
MPC7448 target for u-boot debug with a third
party support and encountered the same result.
GDB console cannot be inserted with a hardware
breakpoint. It was simply reported by BDI2000
with the message 'All breakpoints are in use'.
No matter how you clear breakpoints, problems
still existed. 

In a word, target cannot be stoped by a 
pre-defined breakpoint like board_init_f
in BDI2000 and hardware breakpoints cannot
be set in GDB.

Similar report in archive could be found:

Good luck and happy hacking,

P.S. Pls don't TOP-REPLY. For discuss better,
I changed the thread as the title above.
