-         Xenomai Kernel part.
+         Xenomai is split in two parts: a kernel part and a userspace
+         part. Enabling this option automatically selects the Xenomai
+         package and helps in patching the Linux kernel built by
+         Buildroot with the Xenomai kernel part (ie Adeos/Ipipe).
 
-         In the current version of Xenomai, the following kernel
-         versions are supported: on Blackfin, 2.6.34 and 2.6.36.9, on
-         SH4, 2.6.32.10, on x86, 2.6.35.9, 2.6.37.6, 2.6.38.8, on

-         PowerPC, 2.6.35.7, 2.6.36.4, 3.0.8.
+         You can find the currently supported kernel versions by
+         looking at the available patches in the Xenomai sources
+         tree: ksrc/arch/$(ARCH)/patches
+
+         However, it is recommended to use the latest version of the
+         Adeos/Ipipe patch available at

+
+         Xenomai is know to support Blackfin, SH4, x86, ARM, NIOS2
