How exactly do you define "external debugger"?  Does that mean that
there is an "internal debugger"?  Are you thinking of "bedbug" here?

And in which way is this specific to "Freescale external debuggers"
as you describe it in the Subject?

I don't see where this is specific to the Power architecture either -
expect that you only tested it there.

My understanding is that you enable debug settings for the GNU
debugger.

Do these need to be architecture specific? Probably not.

Do these need to be enabled by a new #define?  What would be the
disadvantages of having these options always enabled, for all
architectures?


Best regards,

Wolfgang Denk
