From 045d8e01516bc793c571107c2766d033af758941 Mon Sep 17 00:00:00 2001 From: Robert Yang Date: Wed, 12 Sep 2018 16:04:33 +0800 Subject: dump_cache.py: Move it from bitbake Add it to oe-core can make it's easier to use, e.g., we don't need use /path/to/bitbake/contrib/dump_cache.py to run it, just use dump_cache.py after the build is initialized.
