# 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
