[yocto] [PATCH 2/3] tiny: Minimize the tiny config
Darren Hart
dvhart at linux.intel.com
Sat Mar 31 07:44:44 PDT 2012
From: Darren Hart <darren at dvhart.com>
The config fragments in the tiny ktype were simply pulled in
from a collection of experimental fragments. Boil things down
to a core policy (yocto.cfg) and tiny-specific configs (tiny.cfg).
