Some questions...

- Which firmware blobs that are *already* in the kernel would need this?
Remember, we're not adding new crap to the kernel source tree; new
firmware images get added to linux-firmware.git instead.

- Why make the include_jump code optional? When would we ever *not* want
to include such a record -- when does the input ihex file contain such
a record that the kernel driver *must* not see because it can't cope
with it?
