The ESPRESSObin from marvell could be a good eval board for testing .If you need it we can send you one. Or we can test new patches here in our company. >> >> Jan, I can help out maintaining the ARM ipipe. We can talk offline >> if you'd like. It would be great if you could keep us up to date on your progress in patching kernel version 5.4.
