Re: [Xenomai-help] Are these results running the xeno-test on a Sequoia board okay?

You need to use adeos-ipipe-2.6.23-ppc-1.6-00.patch for the sequoia
since it still depends on the ppc/ tree, on top of DENX-v2.6.23.8.
Passing --arch=ppc to prepare-kernel.sh instead of --arch=powerpc
without specifying an Adeos patch would pre-select the right one.
