Hi, This RFC series is intended to simplify Flattened Device Tree support, in particular the 'compatible' FDT entry, when Linux names mismatches QEMU ones, but this is the same device modelled.
So far this is only a 'proof of concept'. To see how the qtests perform, I only modified the Xilinx ZynqMP machine. This is only the 6th generic alias compatibility API in QEMU ¯\_(ツ)_/¯ Since v2: - Follow Eduardo advice: "If aliases exist only for compatibility, they should be restricted to the places where compatibility is really needed." - Do not modify QOM/qobject, use a specific GHashTable for FDT alias resolv. - The aliases aren't display in HMP / -device help If a machine is expected to use FDT, it needs to explicitely resolv any device name with the type_resolve_fdt_alias() function. Regards, Phil.
