If you look at the u-boot.map file when building for the ICU862 board
you can see this:
0x40f22b3c __init_end = .
0x40f22b3c __bss_start = .
.bss 0x40f22c00 0x417c
0x40f40000 . = ALIGN (0x40000)
.ppcenv 0x40f40000 0x4000
.ppcenv 0x40f40000 0x4000 common/environment.o
0x40f44000 _end = .
0x40f44000 PROVIDE (end, .)
The #ifdef in "cpu/mpc8xx/start.S" makes sure that clear_bss() does
not attempt to clear any memory that belongs to the environment.

Split it now, and submit any stable parts of it.
