How to install FreeBSD/ppc into a MPC8536 based board?

[Bear]

hi all,
I am a newbie on embedded system. I got a development board which based
on FreeScale MPC8536 chipset. Now I wanna install a FreeBSD on it. Could
you tell me how to do? And which bootlaoder shold I choose? Can U-Boot
work? Is there any resource on this? thx!
I am very sorry that I put a so foolish question here, but I cannot find
any resource on this.
