This is v2 of a patch series that adds support for DM to the MPC8XXX SPI driver, cleans up the driver code, fixes a few minor problems.
Some TODOs are left over for later, such as proper SPI speed setting, and support for SPI mode setting. These would be enhancements to the original functionality, and can come later.
The legacy functionality is removed in this version, so old boards in the tree might end up with broken SPI functionality.
