This set of patches updates the interface to the DDR calibration in preparation for the addition of a pseudo-board for calibration on i.MX6.
The first patch fixes an ommission in the use of the DG_CMP_CYC flag in register MPDGCTRL0. The second patch cleans up the handling of bus widths by passing the system configuration information to the calibration routines. The third patch adds support for returning the calibration data written to the MMDC registers. The fourth patch adds a Kconfig selection to inclut the DDR calibration routines.
