> Commit 99c7cc58e12 ("ddr: imx: Add i.MX9 DDR controller driver")
> contains an inobvious side-effect which renders all systems using
> DRAM controller at 3732 MT/s unbootable. The change is located in
> ddrphy_init_set_dfi_clk(), where the switch case statement entry
> 3732 changed to entry 3733, so any board with DDR calibration data
> for 3732 MT/s operations needs to be updated to 3733 MT/s to match
> the change.
> Since there is currently only one such board, update the board instead
> of handling both 3732 and 3733 options in the driver. It is likely the
> NXP MX8MP RPA update will follow and use the later value too.
