I am suggesting to use Generic platform fw_dynamic.bin and fw_dynamic.elf
for QEMU virt, QEMU spike, and QEMU sifive_u machines.

Do you mean we replace fw_jump.bin with fw_dynamic.bin in QEMU? If
everyone agrees this is the way to go, I can rebase this series on top
of Atish's fw_dynamic.bin support series.

Yes, replace fw_jump.bin with fw_dynamic.bin in QEMU. It will definitely
benefit large kernel images (such as FreeBSD kernel) and it allow QEMU to
decide the FDT placement in DRAM.

I think fw_dynamic makes the most sense. The order doesn't really
matter, but as we are checking in binaries it might be best to avoid
too much churn and rebase this on top of Atish's patches.
