Hmm - does it mean it's currently under development? I couldn't find anything in make xconfig for stock 2.6.24 (running on a PowerMac, but of course with the 44x enabled).
UART works. IIC has recent patches. No idea about SPI.
SPI is probably not too hard. I did some hacks for a slave in an arm920 based environment for that. Here I would need master mode, so I guess some of the infrastructure form drivers/spi can be used.

To load data from an external measurement device which should be connected to the cpu's external bus at a fixed address. It will produce "bursts" which should be shifted out of it without cpu intervention if possible, as it does not have a big fifo, and I must not lose data.
Thanks, Albrecht.
