Please don't do that.

As you can see in Linux kernel activity, there have been a lot activity 
related to the 8xx, including but not limited to:
1/ HW Crypto for the 885 (Talitos SEC1)
2/ TX NAPI in the 8xx Ethernet driver
3/ Scatter/Gather support in the 8xx Ethernet driver
4/ Hugepages
5/ Perf events
6/ hw breakpoints
7/ Linear memory mapping via Large TLBs

We have thousands of boards with mpc885 running and requiring support 
for at least the next 10 years.

How can the 8xx survive without U-boot support ?
