Source: u-boot
Followup-For: Bug #979296
The attached targets.py generates a slightly improved indentation than
the one in previous message.
Also, a redirection was wissing in
# python3 PATH/TO/ATTACHED/targets.py debian/targets > debian/targets.mk
Please use
# python3 PATH/TO/ATTACHED/targets.py < debian/targets > debian/targets.mk
instead.
#!/usr/bin/python3
# Convert debian/targets to a Makefile snippet included by
# debian/rules.
# python3 debian/targets.py < debian/targets > debian/targets.mk
