I'd really like an overview what I would need to port U-Boot to the Motorola MVME5500.
See section "U-Boot Porting Guide" in the README.
I've seen in the source, that there's support for an evaluation board featuring this controller - EVB64260. The CPU seems to be supported as well by the 74xx_7xx, as far as I can see.
Correct.
But I do need some starting points of how to know which code to adapt, how to rewire the existing code, which data to supply to make it correspond to my setup.
Well, even if you cannot implement the function no_more_time() the rest of the "U-Boot Porting Guide" still applies. Follow it step by step.
BTW: MCC Systems sells a "Linux SDK" which includes a port of U-Boot to the MVME5500 board (see http://www.mccengineering.com/linuxsdks.htm)
Maybe we should start a "black list" of companies who don't give their patches back to the public source tree.
