# We want to generate two device tree blob (.dtb) files by combining
|
|
# the "base" and "add" device tree source (.dts) files in two
|
|
# different ways.
|
|
#
|
|
# 1) Use /include/ and compile via dtc to make the "gold standard"
|
|
#
|
|
# 2) Compile them separately dtc, and join them with the
|
|
# ufdt_apply_overlay program
|
|
#
|
|
# Then, compare 1) and 2) with dts_diff (diff merged nodes) and return 0
|
|
# iff they are identical.
