[U-Boot] [PATCH v1 2/3] ddr: vybrid: Provide code to perform on-boot calibration

2018-12-02 Thread Lukasz Majewski
This patch provides the code to calibrate the DDR's DQS to DQ signals (RDLVL). It is based on: VFxxx Controller Reference Manual, Rev. 0, 10/2016, page 1600 10.1.6.16.4.1 "Software Read Leveling in MC Evaluation Mode" and NXP's community thread: "Vybrid: About DDR leveling feature on DDRMC." http
