Ye Li 662f05fcb6 ddr: imx9: Add workaround for DDRPHY rank-to-rank errata ... According to DDRPHY errata, the Rank-to-Rank Spacing and tphy_rdcsgap specification does not include the Critical Delay Difference (CDD) to properly define the required rank-to-rank read command spacing after executing PHY training firmware. Following the errata workaround, at the end of data training, we get all CDD values through the MessageBlock, then re-configure the DDRC timing of WWT/WRT/RRT/RWT with comparing MAX CDD values.
