If you are using embedded linux, you probably have an ip-connection to
the hw and uboot as the fw/bootlooder/bios or what you prefer to call it.
If you have an ip-connection, you can just ssh to the box and copy it to
the right place and do whatever is needed.
You usually don't update the processor, embedded board or other fw
than uboot. If you want to do that you have to check the manufacturer
documentation.

Ack, here is example manufacturer documentation of the process:

That hw is similar to the BeagleBoneBlack mentioned by Antoine,
so if you start off the BBB, this one could be the next in your
learning curve.
