plan to add kdb support for ARM/XScale architecture support

[Dong, Edie]

Dear sir/madam:
             I am planning to add Xscale architecture support for KDB, I
want to fully use the XScale HW debug unit to enable the instruction break
point and data breakpoint as well as the trace buffer enabling. Of course I
am going to make it have limited feature support for ARMV4 architecture
system.
             Does any body have any suggestion or comments? Or is there
anybody already devoted to this area? 

best regards, eddie
