Hi. First off, I've included the linuxppc-embedded mailing list in my reply. It's better to mail the list and CC: me rather than just mailing me. There are many others far brighter than me on the list who can provide far more help.

If so, the first patch provides the generic SPI infrastructure. Device drivers for SPI masters and SPI slaves register to the SPI subsystem. That way SPI master device drivers are decoupled from SPI slave device drivers. It follows the new device model in the 2.6.x kernels.

Eventually I'll have a public git tree with all my changes posted in it; but not yet. > How can I contribute to this effort? Write code, write documentation and post patches. Also, look in the LKML archives. There are two other competing SPI implementations that are being developed. I've been pulled off onto other work so I've not done any additional work. The other code looks more promising. That being said, my code works for me so it may be usable for you as-is. cheers, g.
