Dear Roy Zang,

This patch adds general Freescale powerpc external debugger support. Patch is tested on 85xx/QorIQ platforms in u-boot with CodeWarrior. CONFIG_EXT_DEBUGGER should be defined if the u-boot needs to be debugged by external debugger. To use the external debug funciton, the make command can be just as make CONFIG_EXT_DEBUGGER=1 or define CONFIG_EXT_DEBUGGER in the board header file.
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
