#
# This test uses a Linux kernel built from unmodified vanilla kernel sources
# but using a slightly simplified kernel configuration, as well as device tree
# for a minimal Versatile Express Cortex A15 like emulated board.
#
# The used sources, including the modified device tree and configuration file
# can be found in the following git repository/branch:
#
#   https://github.com/skalk/linux/tree/vexpress-vt
#
# To compile the kernel and device tree blob used in this script, do the
# following steps:
#
# ! git checkout https://github.com/skalk/linux.git
# ! cd linux
# ! git checkout origin/vexpress-vt
# ! make ARCH=arm CROSS_COMPILE=<cross_compiler_prefix> vexpress_config
# ! make ARCH=arm CROSS_COMPILE=<cross_compiler_prefix> -j8 Image
# ! make ARCH=arm CROSS_COMPILE=<cross_compiler_prefix> vexpress-v2p-ca15-tc1.dtb
#
