... 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.
