== Introduction ==
Quilt is a little tool used to manage patches. The project is hosted on [http://savannah.nongnu.org/projects/quilt savannah forge] and can be found in debian package repository.

== Using quilt in ARMadeus project ==

Quilt is useful when linux kernel or buildroot modification must be done. Because ARMadeus use official linux/buildroot sources, each specific modification for our platform must be done with a patch. And patches are versionned on ARMadeus sourceforge repository in directory /home/fabien/Projects/exer/software/bsp/buildroot/target/device/armadeus/linux/kernel-patches/ for Linux kernel and in patches/buildroot for buildroot.

To use it under ARMadeus Project, a simple script was written to simplify it : ''quiltify.sh''. Launch it from the root project :

<pre class="host">
[ ] $ ./scripts/quiltify.sh
</pre>

Then answer questions (defaults are recommended). For linux kernel, quiltify will rename your source directory and download/patch/compile again the sources.

Once you done it, you can go to linux sources directory ''buildroot/project_build_armv5te/apf27/linux-2.6.29.6'' then list all patches applied to with quilt command :
<pre class="host">
[ ] $ quilt applied
015-armadeus-logo-add_armadeus-project_tux.patch
016-armadeus-imxfb-add_platform_specific_init_exit_functions.patch
018-armadeus-i2c-imx-add_driver_to_linux_build_system.patch
…
336-armadeus-imxfb-makes_it_compatible_with_arch_imx.patch
337-armadeus-imxfb-add_lcd_clock_def_for_imx_platform.patch
338-denx-mxcgpio-emulates_interrupt_on_both_edges.patch
339-apf27-armadeus-spidev.patch
</pre>

If you want to create a new patche, just use ''new'' quilt command. Then '''before''' modifying linux file, add it to quilt with ''add'' command.

The file can be modified according to your wish.

Once modification done, you can generate the patch using ''refresh'' command. To add yours patches in the right directory, go to your project root then launch the script with ''export'' command :
<pre class="host">
[ ] $ ./scripts/quiltify.sh export
</pre>

Your patch is now ready to be committed on ARMadeus sourceforge.
