From 0b3c71621fb302f59a458b6bc36ca318fe756a6b Mon Sep 17 00:00:00 2001 From: Robert Yang Date: Thu, 25 Aug 2016 07:40:58 -0700 Subject: qemuboot.bbclass: add it for runqemu It saves vars in ${DEPLOY_DIR_IMAGE}/.qemuboot.conf, and runqemu will read it. The bsp which can be boot by runqemu will inherit it.
