I am cuurently trying to boot up the linux kernel using ppcboot 1.16 and the
2.4 kernel with only smc1 uart support as a start on an MPC860 FADS derived
board.

Which 2.4 kernel? Please be precise.

So far I have:
- ppcboot running great
- tftpboot graps my kernel puts in RAM
- bootm starts my kernel ... BUT no serial activity ...

This is a FAQ. See the Q&A section in http://www.denx.de/re/DPLG.html
Either you're passing a wrong bd_info structure,  or  a  wrong  clock
frequency  (see  also  the  PPCBoot  README about the "clocks_in_mhz"
stuff.)

I am using the vision ICE currently to debug the kernel start up but it has
a problem stepping through the 'rfi' etc when memory protection is running.

You cannot step through rfi, not with any BDM debugger.

Best regards,
