I think this is the best way to do it - there's already a ppc_md struct
kicking around which is semi-meant for this kind of thing.

Good. It might actually happen if enough of us want it to :-)

Yes, but I'm more than willing to pitch in with the Freescale guys if
that'll get things done faster - they've obviously got more manpower. I
wanted to get this thing done already! :-)

I don't use it. I have a very simple bootloader which I use on our Memec
based design - comes in straight off sysace and jumps at the kernel
after doing simple diagnostics, avoided the need for porting an existing
boot loader and it's reasonably able to cope with braindead Xilinx HALs.
