This patch adds a basic auto-tools configuration environment for the bootwrapper consisting of the configure.ac file and the Makefile.am file. The configure.ac file includes several options and checks: - Ensure that an AArch64 compiler is used. - Add the mandatory --with-kernel-dir option that sets KERN_DIR. - Check that the correct base dtb file exists in KERN_DIR. - Add an option, --with-initrd, that allows a user to specify an initrd file to embed in the image. - Check for a working dtc and set DTC to the full-path to the executable. - Create the necessary symbolic links to the relevant kernel files. The Makefile.am file includes several changes: - Use a prebuilt dtb rather than a dts, which is decompiled to inject the chosen node. - Use the configured compiler tool names. - Use the configured SED program rather than assuming it is in PATH.

Linux boot wrapper with FDT support =================================== To get started: $ autoreconf -i $ ./configure --host=<toolchain-triplet> --with-kernel-dir=<kernel-dir> <other-options> $ make Where: - <toolchain-triplet>: this is something like aarch64-linux-gnu - <kernel-dir>: the directory containing a pre-built aarch64 kernel and its sources. - <other-options>: see ./configure -h for a list of other options.
