The build instruction is the following (for 8.x and 9-CURRENT):

<< assuming the FreeBSD source tree is your current working dir >>

1. Cross build E500 PowerPC world
$ make buildworld TARGET_ARCH=powerpc TARGET_CPUTYPE=e500

2. Cross build MPC85XX kernel
$ make buildkernel TARGET_ARCH=powerpc TARGET_CPUTYPE=e500 KERNCONF=MPC85XX

There's also some old wiki notes for booting MPC8541, some of the material is outdated, but most should still apply http://wiki.freebsd.org/Eval8540Boot

We really should have a better documentation and an up to date wiki pages for running Book-E...
