OK, noted, thanks.

We have a patch ready to make the frequency adjusted at runtime that
should be on the mailing list in a day or so, as suggested by Vignesh,
targetting uboot-next, this one fix should go into master however.
Thanks,

[PATCH] arm: dts: k3-am625-verdin-r5: Change CPU frequency to 800MHz
From: Joao Paulo Goncalves
The lowest speed grade of Toradex AM62 SoMs is K speed, resulting in a
max value of 800MHz for the CPU operating frequency. A solution with
runtime selection of the CPU frequency is already planned to avoid these
kinds of problems in the future.
Fixes: 8fb8a6d49977 ("arm: dts: k3-am625-verdin-r5:Change CPU
frequency to 1000MHz")
