PCIe ain't a mostly dumb parallel like ISA or Zorro it ain't even something like PCI were you only needed a few extra pins for each slots (and even those were optional when you didn't mind sharing the bandwidth), it is a protocol were each lane is a connection between 1 host and 1 target.
Thanks for teaching me what PCIe is and isn't. This is exactly why I come to this forum every day: to learn.
Look, today GPUs have a PCIe interface making a connection to PCIe simple and cheap.
An SoC like AEon is using, might not have the right type of PCIe interface, the CPU can access PCIe but I don't know if they can be used as 'Slaves' in a bus system where others are masters.
I don't know much about this modern Busses, maybe AEon would have to develop their own bridge chips for a proper connection. SoCs are usually designed to be the master in a system, they don't share resources like RAM with others.
And one of the main thing that's lacking in the AmigaOne/AmigaOS4 market are hardware developers developing hardware for AmigaOS4, designing such a card will make everything worse.
