I think you should go ahead.
I am also interested in your driver stacking, as I have code to provide some
framebuffer support for ST7575(MBed, Eadog128), Ili9341( F429/MR24
Discovery), Sharp LS013 (Display from the Zero Gecko) and SEPS525 (DD160128
Oled Display) and try to integrate it into nut/dev.

The LSB SPI transfer is needed for the LS013.
Thiago, could you perhaps provide LSB transfer for AVR32?
Any SAM7 user: Does Sam7 allow SPI LSB transfers? A short scan through the
AT91SAM7 datasheets gives me the impression that the SPI peripheral doesn't
provide that capability.
Where to put a Bit reversal generic into ethernut?

Thanks
