With the ability to have the USART in (master) SPI mode, and with some of the larger Atmel chips having several of them, how does one go about having the various SPI libraries work with a different SPI port? As far as I can tell, most (if not all) of the current libraries for devices using SPI, are…

AVR allows the same according to ATMega chip docs, but I don't know if we have a library for the hardware.
Having hardware shift the bits in/out saves a constant load on the processor.
