Support fuse cmd to read/write fuse. Power supply for fuse should be ready, name is VDD_EFUSE in some schematic.

Mmh, in general I am not sure it is a good idea to expose this so easily to the user. I guess a clueless user can easily brick his board by typing something at the "fuse write" command. I understand that one has to manually enable the fuse command first to allow access, but this is still quite a high risk, especially since a lot of the fuses are not documented. Would love to hear opinions from others about that topic.

I agree.
