I want to port RedBoot to a PowerPC 7400 platform and there are some 
problems confused me.
1. Need I porting the whole HAL to the new platform?
2. Besides HAL, how many other modules also need I port?
3. If redbot's debug functions are necessary, need I do some work with gdb?
4. Are there something special for building and installing?

In addition, is there anyone who is doing something like this?
beg your help.

See the Porting guide 
http://ecos.sourceware.org/docs-latest/ref/hal-porting-guide.html

You should only need to do a HAL varient port since the PowerPC is
will supported. You might also need to write a serial device driver,
ethernet driver, watchdog, hardware dependent flash driver etc, it all
depends on your hardware and how much it is like some other device
which eCos supports.
