Well, my misunderstanding? Suppose FLASH size is 
4, 8, 16 Mbytes, could we set 
TEXT_BASE=CFG_FLASH_BASE=CFG_MONITOR_BASE as
0xfc000000
or 0xff000000 for a low-boot situation? If so, there 
should NOT any change for the source code itself.

To my understanding, for a low-boot ppc like 8xx 
target and programming image to FLASH to debug,
TEXT_BASE should equal to CFG_FLASH_BASE and 
CFG_MONITOR_BASE as FLASH size or its several times.
Am I right?

Thanks in advance!

Sam
