Driver with extended SPI used on non-Due processor.

Are there any other processors besides the one used in the Due that will work with the extended SPI commands but have a smaller, easier to solder pin count? I have a display driver where the demo's and driver are only written for the Due and will not compile for any of the other boards that I have tried. Messed with trying to convert the extended commands to standard SPI but its a rabbit hole beyond my current knowledge. I would use the Due processor in my project, but cannot reliably solder a 144 pin LQFP or any kind of BGA which are the only packages available for the SAM3X8E. Options?

Please define "extended SPI commands"!

And why didn't you post a link to that driver?
