This does not help. If I use the NXP U-Boot I can boot the NXP 5.4.3
without problems.

Currently, we can not even boot to the U-Boot prompt with mainline U-Boot.

Reverting f24dea4e1b ("ARM: imx8m: Fix reset in SPL on NXP iMX8MP
EVK") allows it to boot again.

As discussed in the other thread, this means that the i.MX8MP clock
driver is broken.

Please let me know if you can look at these issues.
