... why do you encode a kernel command line at all when this
information gets passed to the kernel by U-Boot?

This doesn't make sense to me. I recomnmend to check the passing of
the boot arguments again, as outlined in the FAQ mentioned above.
Attach a debugger and check what your kernel is doing. At least trry
a post-mortemn dump of the log buffer (see FAQ).
Anyway: I don't see how all this is related to U-Boot. Seems to be
kernel problem and as such somewhat off-topic here.
