Ok, so if you have the firmware source, add a proper make file and the source along
with the binary file. You made it sound like the you only had the firmware as
a hexdump, which would not be possible under the GPLv2 section 3, which says
"The source code for a work means the preferred form of the work for making
modifications to it".

That part is fine, what is not fine is the "All rights reserved" portion, which
contradicts the GPL.
