If you do a search for 'SPI layer' in the uClinux mailing list
archives, you should find a thread about this.  A few people provided
layered MCF SPI support for 2.4.  The original author had two drivers
written in it and I have written one using it.  It seems to work well.
 I'm not sure if it is going to end up in the main tree or not,
though.
