Yes that could be the case. We use the Linaro-version of u-boot
(git://git.linaro.org/boot/u-boot-linaro-stable.git) on the
'Linaro-u-boot-2011.12' branch. The behavior you describe though, kind
of looks like as if the I/O memory base of the controller might be
wrong. What version of the PandaBoard do you use? We only tested the
thing on ES.
