I've reviewed and applied the 01-cbusx.patch.
Thanks for this high quality contribution.

How did you generate the patch file? Using "Write commit to file" in gitk?
Please use "git format-patch HEAD~XXX" the next time. Then I can just
apply them via "git am" without manually copying the commit msg etc. over.

Regarding the ftdi_eeprom patch: It alters the current behavior.
If someone uses "--erase" together with "--flash", it is no longer possible.
Imagine someone wants to flash a shorter eeprom than
the one that's currently on the chip, then "--erase"
is really helpful to ensure there's no garbage left.

What do you think?

Cheers,
Thomas
