Is your objective simply a faster boot? We don't have any specific plans to add SPL support for Nitrogen6x, but are interested in hearing what you're after. > I'm guessing all the work I'd need to do is in board/boundary/nitrogen6x? > Also how would I normally configure and build an spl for > a working board.

Does it really boot faster though? Do you have any numbers for TTP (Time-to-penguin) on a SABRE Lite or SABRE SD? Regards, Eric
