I've applied Xenomai patch from xenomai-head
commit 0ce3ed58074fa4d593ba556157d1edc288aff3f1
Author: Philippe Gerum <[email protected]>
Date: Wed Dec 14 10:46:27 2011 +0100
powerpc: upgrade I-pipe support to 3.0.13-powerpc-2.13-06,
ipipe-3.1.5-powerpc-2.13-06
to linux mainline 3.1.5 kernel.
The board is a P2020RDB where I've used defconfig: mpc85xx_smp_defconfig
Please advice.
