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.
