The fby35 machine was deprecated in QEMU 10.2 and is now removed in QEMU 11.1. This multi-SoC machine was added as an example of heterogeneous systems, but the models never evolved and no public firmware is available to boot it. Users needing multi-SoC emulation should use the ast2700fc machine instead, which is based on newer AST2700 SoCs with better support.
