Comet Lake U, "-p internal" not available?

[Rafael Send]

Hi,
I'm trying to flash laptop that has an i7-10710u on it. From what I've been
told, it's not officially supported yet but works if I build from source.

I did so, but when I try running it I'm told "-p internal" is not a valid
programmer. How can I use that method of programming on the latest master?

I've used the internal programmer on previous versions / different boards
so I aware of the risks and have methods of recovery, but I'd prefer to
start with flashrom for ease of use.

Thanks,
Rafael
