Hello, all:
    Would you like to provide me with the source codes of LinuxPPC initialization for MPC8xx, just from the CPU PWRUP Reset to the OS and finally to the Application ? If available, the corresponding documents will be OK!
    Thank you for your help!
    Best Regards!

It seems you are  looking  for  PPCBoot,  the  Open  Source  firmware
project  for  embedded  PowerPC  systems.  It's  running  on many PPC
systems, including 8xx, 82xx and 40x CPUs.

The project page is at ppcboot.sourceforge.net .  It  contains  hints
how  to  access the anonymous CVS server at sourceforge where you can
find the latest and  greatest  versions  of  PPCBoot.  You  can  also
download the tarball of the "official" released versions from our FTP
server, see ftp://ftp.denx.de/pub/ppcboot .

For PPCBoot related questions you should  join  the  PPCBoot  mailing
list - see http://ppcboot.sourceforge.net/#mailinglist

Wtao,

You can also find CPU PWRUP code for the MPC850 in the QSLinux release,
downloadable from ftp://qslinux.org.  It contains code to "kick" the
watchdog as it decompresses the kernel.  It also provides a very
flexible scheme for configuring processor clock speed, console port
setup, etc.  Documentation can be found at http://qslinux.org.

This is available in PPCBoot as a configurable option,  too  (and  we
have  submitted  a  watchdog  driver  for  Linux  2.4.x to the kernel
maintainers).

And PPCBoot is not limited to the 850.

Everything (and more) is available in PPCBoot, too.
