Hello,
I've ported SPI driver form arm-linux to ecos(AT91M55800A) not so long ago.
I used it with Dataflash memory.
It has some issues:
1. The speed rate doesn't rise beyond 320 Kbit.
I've applied to the Atmel's support but didn't get a satisfactory answer.
2. Sometimes the spi device doesn't answer the command.
Probably these are peculiarities of AT91 SPI or my bugs.
I could send it to you.
By the way there is Atmel's software SPI driver.
-------
Regards,
Mike
