Many (most?) devices can't boot raw kernel using tftp and probably none
allows flashing it. It's way more usable to have TRX with kernel
containing initrams as such an image can be actually flashed.

Some devices may support tftp flash booting and it would be the best to
have both images generated for them. Unfortunately it's not possible
right now (only one initramfs image can be generated).

Please exclude buffalo devices from this change. You can press a button
that makes it load firmware.lzma via TFTP from 192.168.11.1.
