So I am not  sure whether freebsd8.0 is ok on mpc8572. If I want to run freebsd8.0 on mpc86572pc, does I need to modify freebsd8.0 code? How should I do at first step?

Patrick,
The 8.0-CURRENT has rudimentary MPC8572 support (single-core, silicon rev1.0
only).

Please note that full SMP support (and all SOC peripherals drivers) is being
or already is developed -- please contact me if you're interested in more details.

As far as U-Boot goes, ver1.3.2 would not have support for any MPC8572-based
system: coincidentally, patches with support for MPC8572DS were posted to
u-boot mailing just today! You can either apply them yourself, or get the
ready to use sources/binaries from Freescale.

kind regards,
Rafal
