[avrdude-dev] UC3C support

[Marco Nilsson]

I’m trying to add support for UC3C devices. These devices use a 4 byte JTAG 
identifier, such as 0xr200003F where ‘r’ is the revision number. The problem 
here is that avrdude only allows 3 bytes for signature, and no wildcards. This 
means that I will either get a parse error when using 4 bytes, or the 
signatures will not match.

Is there any way to extend this to 4 bytes and maybe even add wildcard bits?
