You have to provide a working root filesystem in the first place.

This is normal. If you use U-boot  there  is  no  need  to  have  any
pre-compiled  boot arguments; more: there is no need to use the whole
bootstrap loader which supplied these precompiled bootargs.

Just define the required bootargs in U-Boot.

Do not ignore this error. How big is your cramfs iage? How  much  RAM
do you have?

Is there any chance that you built your cramfs image on a x08 (or any
other little-endian) system and forgot  to  give  the  "-r"  (reverse
endian-ness of filesystem) option to mkcramfs??
