OpenEmbedded or anything similar.)

+
+Kernel build scripts
+====================
+
+This is a collection of scripts to build the Linux kernel. This is the "manual"
+build process, which only needs a cross-toolchain and u-boot, but nothing else
+from OpenEmbedded or any similar environment.
+
+They're mainly intended as examples for how the process works and aren't
+necessarily useful "as is" for daily work:
+
+build
+  Build the kernel from scratch, using either the latest or some specific
+  version from the ftp.kernel.org kernel (HTTP) and the OpenMoko patches (SVN).
+
+update
+  Update the kernel sources to either the latest or some specific SVN version.
+
+
+Toolchain
+---------
+
+We use the OpenEmbedded EABI toolchain. See ../../u-boot/scripts/README for
+details.
+
+
+Environment variables
+---------------------
+
+See "build".

+#
+# This script illustrates how to build a specific version of the Linux kernel
+# from scratch. This is mainly intended as a template for copy & paste, and as
+# an example for individual scripts.
+#
+# This script uses the gnueabi toolchain, see the file
+# ../../u-boot/scripts/README in this
+#
+#
+# Environment variables:
+#
+# SVN points to the root of the local copy of the OpenMoko SVN tree (the tree
+# must be checked out already), e.g.,
+# SVN=/home/moko/svn.openmoko.org/
+#
+# KERNEL specifies the kernel version we use, e.g.,
+# KERNEL=2.6.22.5
+#
+# KERNELSRC_DIR, if defined, specifies the directory where the kernel source
+# tarball resides. By default, we use ".".
+# KERNELSRC_DIR=/wherever
+#
+# UBOOT_DIR, if defined, specifies the absolute (!) path to the directory where
+# u-boot has been built. By default, we use ./u-boot
+# UBOOT_DIR=/wherever/u-boot
+#
+# SVN_REV, if defined, specifies which SVN revision we use, e.g.,
+# SVN_REV=3770
+#
+
+# wget http://ftp.kernel.org/pub/linux/kernel/v2.6/linux-${KERNEL}.tar.bz2
+
+tar xfj ${KERNELSRC_DIR:-.}/linux-${KERNEL}.tar.bz2
