Add xenomai real-time Framework to buildroot
[Fixes by Thomas, including comments from Arnout: * Use AUTOTARGETS instead of GENTARGETS * Use $(KERNEL_ARCH) instead of $(BR2_ARCH) as argument to the prepare-kernel.sh script. This allows the arch name to be fixed with the usual sed expressions and the quotes to be stripped. * Add the --verbose option to prepare-kernel.sh. This allows to get some clear error message when no Xenomai patch has been found for the current kernel version. * Improve the help texts as suggested by Arnout, and remove the now useless README file. * Add a BR2_PACKAGE_XENOMAI_SMP option, instead of poking inside the kernel configuration to find out whether SMP is enabled or not. This cannot work because: 1) the kernel might be built outside of Buildroot and 2) if the kernel is built inside Buildroot, it is built *after* Xenomai, so the kernel configuration file is typically not yet present. * Simplify the ARM subarchitecture selection as suggested by Arnout. * Remove the documentation and development files according to Buildroot standards (using BR2_HAVE_DOCUMENTATION and BR2_HAVE_DEVFILES). * Simplify the /etc/ld.so.conf modification logic. ] [Peter: whitespace fixes] Signed-off-by: Benoit Mauduit <benoit.mauduit@openwide.fr> Signed-off-by: Thomas De Schampheleire <thomas.de.schampheleire@gmail.com> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

+ Real-Time Framework for Linux
+ http://www.xenomai.org
+
+ Xenomai is split in two parts: a kernel part and an
+ userspace part.
+
+ This package contains the userspace part, which consists
+ mainly in libraries to write userspace real-time programs
+ that interact with the in-kernel Xenomai real-time core.
+
+ For those libraries to work, you need a Xenomai-enabled
+ kernel. This is possible in two ways:
+ - if you compile your kernel with Buildroot, you need to go
+ to Linux Kernel -> Linux Kernel Extensions to enable the
+ Xenomai extension.
+ - if you compile your kernel outside of Buildroot, you need
+ to make sure that it is Xenomai-enabled.
+
+ Finally, if you are using a static /dev, make sure to
+ uncomment the Xenomai entries listed in
+ target/generic/device_table_dev.txt.
