To allow a slave driver to specify the 8-bit transfer we'd like to make this change to the spi_transfer data structure. We are still working on the driver we will send an RFC for the driver patches separately once it is ready.

Please don't send cover letters for single patches, if there is anything
that needs saying put it in the changelog of the patch or after the ---
if it's administrative stuff.  This reduces mail volume and ensures that 
any important information is recorded in the changelog rather than being
lost. 

Please fix your mail client to word wrap within paragraphs at something
substantially less than 80 columns.  Doing this makes your messages much
easier to read and reply to.
