Oh, sorry, forgot reply this item.

And I have no related hardware (I am just cross compiling).

Hmm... according to the implementation, we can assume original author
though: "currently only H8300H_AKI3068NET and H8300H_H8MAX can/need
support NE_H8300" (may better use "need" instead of "can").


Thanks.
