We surely can if we find developers motivated to do the work. Regards, Phil.

Still, having machine memory size depending on the host config was a bad design choice IMHO, as we test different setup depending on the host being used, so not really a "reproducible" setup.

I just don't think adding more machine names where only RAM size is different would be better than using -memory for that as usual. Regards, BALATON Zoltan

Allow to create the following machines: - Zero2W - 400 - CM4 and CM4S Fill the arrays with the BCM2712-based machines (raspi5), but since we don't model the SoC, these machines can't be created (and aren't listed in the 'help' output).
