Bootloading and programming Atmega 1281

Hello, and thanks for your time;

I've been reading various forums and github repositories and I've been seeing a mixed bag of answers as to whether or not a Atmega 1281 can be programmed and bootloaded with just the SPI interface.

I went through the data sheet and it states that any interface can be used to program it, but bootloading with SPI interface may be limited on "Some select devices". Does anyone know if the 1281 is one of the blacklisted devices?
