No, unless you want to access it somehow in U-Boot.

In general, you *want* to have a driver to be able to use U-Boot to update itself.

2. If it is correct to set the values of CFG_FLASH_BASE, CFG_MONITOR_BASE

and TEXT_BASE like this: CFG_FLASH_BASE=0xC2000000 CFG_MONITOR_BASE=0xfff80000 TEXT_BASE=0xfff80000

This may or may not be ok. We don't know your hardware.

3. I saw CFG_RAMBOOT in Start.S and CFG_LOWBOOT in MPC8260ads.h.What is the

You better forget these. See the FAQ.

meaning of them,sorry I am blunt to software.

Ummm... porting U-Boot requires a certain level of qualification...
