After activating the SPL clocks I see:

 clk          69  [   ]   imx_clk_gate2         |   |
`-- dram1_root_clk

The dram1_root_clk is not getting turned on.

This clock is marked as CLK_IS_CRITICAL, but it seems that U-Boot core
clock driver does not handle it yet.

I have also tried to enable it manually by doing:

clk_get_by_id(IMX8MP_CLK_DRAM_CORE, &clk);
clk_enable(clk);
clk_get_by_id(IMX8MP_CLK_DRAM1_ROOT, &clk);
clk_enable(clk);

but it did not work.

The complete clock dump is here:
