There We also have the sam460ex for 440 based CPU that runs with Linux as another test but having more than one is better and not sure if the sam460ex has an acceptance test in QEMU. (I think Guenter Roeck tests sam460ex with Linux at least he did in the past.) By the way what happened to the test written by Philippe for pegasos2. Is that upstream yet? That test used MorphOS so we don't only test Linux (but it needs the iso which is freely downloadable but probably not redistributable due to its license). And that's not a BookE CPU so maybe off-topic in this thtead I was just reminded of it. > is not much effort in keeping them in a working state until someone > volunteers.

It is not clear to me if u-boot is I think the SDRAM init could be fixed by adding SPD data, I've done that for sam460ex, I may try to look at cleaning up the memory controller models together with the 440 one as these are similar but not too high on my list I want to do now so maybe later if 405 will be kept.
