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.
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. -Matt
