[U-Boot] [PATCH 00/19] spi: mpc8xxx: DM conversion

[Mario Six <mario.six@gdsys.cc>]

This patch series 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 retained, so older boards will still work
after the patches are applied.
