+Patches in with-linux-3.4
+=========================
+
+These patches were adapted to apply on Linux 3.4 from the ones found here:
+
+http://sheeva.with-linux.com/sheeva/kernel/3/3.2/3.2.9/source/
+
+They assume the Dreamplug has the original u-boot shipped by Marvel. This
+means that the kernel will expect it to report the Guruplug machine id
+2659 instead of the official 3550, and it assumes u-boot doesn't provide
+a flattened device tree. If your u-boot uses the Dreamplug id then you
+can just remove the section about linux-3.4/arch/arm/tools/mach-types
+from dreamplug-3.4.0.patch. If it also provides a flattened device tree,
+then you don't need dreamplug-3.4.0.patch at all.
+
+Using the kernel patches
+------------------------
+
+Instructions based on freedom-maker's README [1].
+
+To compile your own kernel, you can use config-3.4.0-1bauer2-kirkwood as basis.
+Follow the following steps on the DreamPlug to compile a new kernel:
+
+ 1. Get the kernel source and other needed packages.
+ # apt-get kernel-package lzma quilt
+ 2. Get the Linux 3.4 kernel.
+ # wget https://www.kernel.org/pub/linux/kernel/v3.0/linux-3.4.tar.bz2
+ 2. Unpack it somewhere.
+ # tar xfj linux-3.4.tar.bz2
+ 3. Apply the patches found in with-linux-3.4.
+ # cd linux-3.4
+ # ln -s ../with-linux-3.4 patches
+ # quilt push -a
+ 4. Copy the config and compile.
+ # cp ../config-3.4.0-1bauer2-kirkwood .config
+ # make-kpkg clean
+ # make-kpkg --append-to-version -1bauer2-kirkwood --revision=3.4.0-1bauer2 --initrd --cross_compile=- kernel_image kernel_headers
+ 5. Install the packages.
+ # dpkg -i ../linux-{image,headers}-3.4.0-1bauer2-kirkwood_3.4.0-1bauer2_armel.deb
+
+After kernel is installed on device, hooks should be calling:
+ # flash-kernel 3.4.0-1bauer2-kirkwood
+
+After that you should get a uImage and uInitrd files under /boot.
+
+These packages should get a kernel up and running into DreamPlug device.
+The compilation process takes 6 hours on the DreamPlug. You will need
+approximately 1 GB of free space for the build (including the size of the
+unpacked kernel source).
