Nice work, specifically as it already considers a separation between
hw-specific and generic part. I guess we just need one further SPI
application/hardware driver to get a kick-off for an RTDM profile (I
personally don't feel like I could judge on an SPI API design ATM).
Meanwhile I would suggest to link your work also via the wiki
(=>weblinks) so that others can find it that way.

Yes, that sounds fairly interesting as well. Given that we already have
a profile here and a fair amount of users, integrating some Blackfin
UART RTDM driver into Xenomai mainline wouldn't likely be a big deal.

Once finished, you are welcome to post it, review will be provided ASAP.
Please choose kernel coding style right from the beginning to accelerate
the review.
