Searching this list and the U-Boot repository, I found that this problem was
already acknowledged by Wolfgang once back in 2004:
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/12197

Soon after that, there was this fix ("Fix endianess problem in cramfs code"):
http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=commitdiff;h=36c728774edcfca54766f6828173fe24d3d8aa0b

But then, this fix got reverted by the following change in 2005:
http://www.denx.de/cgi-bin/gitweb.cgi?p=u-boot.git;a=commitdiff;h=b66eb5282d568225abad5b3b61cc0968be35fc0d

At last, the issue popped up on the list again in 2006 (the post that I'm
replying to):
http://article.gmane.org/gmane.comp.boot-loaders.u-boot/22846

Thus, I suggest that the original fix should be re-applied.
