> From: Emanuele Ghidoli <emanuele.ghidoli at toradex.com>
> Update LPDDR4 configuration and training using updated spreadsheet and
> tools from NXP using data from previous spreadsheet and verified
> toward datasheet:
>  - MX8M_Plus_LPDDR4_RPA_v9.xlsx
>  - mscale_ddr_tool_v3.30.exe
> From:
> https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/i-MX-8M-Family-DDR-Tool-Release/ta-p/1104467
> Some register values differ due to these fixes/modifications:
> - corrected calculation of T_CKPDX parameter (equal to tCKCKEH for LPDDR4)
> - corrected ECC related items, none of which affect normal operation
>   when ECC is not enabled
> - corrected formula for calculation of tRTP in cell D122
