I have a custom 405GPr board containing 64M ram and 4M flash with no PCI
connector, just ethernet and ttyS0/1 to outside world. I am able to load
and run simple ppc code to ram using a Macraigor JTAG debugger via
insight/gdb using gnu tools provided by them.
What would it take to get linux running on this board? Any pointers or
suggestions would be appreciated.
Thanks,

Port u-boot using walnut code as an example.
Copy the Linux walnut code to foo_board.[c|h]. Remove what you don't need
from the files. Modify other things accordingly. Update the
Kconfigs/Makefiles.
Unless the hardware is buggy, it should be very straightforward. You
can even proof of concept things by loading vmlinux from your JTAG
debugger and setting r3-r7 appropriately...skipping the firmware stage.
