This is a relatively low-cost AST2500-based Amd Ryzen 5000 Series
micro-ATX board that we hope can provide a decent platform for OpenBMC
development.
This initial device-tree provides the necessary configuration for
basic BMC functionality such as serial console, KVM support
and POST code snooping.
