I did consider it but it would involve messing about with filter to remove
the test from the wildcards. This way we don't forget about it when looking

The 'virt' RISC-V machine has a lot of instances where MachineState

Hi,
In this version I included a rework in riscv_load_fdt() to separate the

same function doesn't give us much and can lead to confusion due to how
other archs handle their respective load_fdt() functions.
Patches are based on
A common trend in other archs is to calculate the fdt address, which is
usually straightforward, and then calling a function that loads the
fdt/dtb by using that address.
riscv_load_fdt() is doing a bit too much in comparison. It's calculating
the fdt address via an elaborated heuristic to put
