Author: jhibbits Date: Fri Jul 20 16:18:24 2018 New Revision: 336555 URL: https://svnweb.freebsd.org/changeset/base/336555 Log: vt/ofwfb: Fix brain-o from r336514, use the correct form of /chosen/stdout-path /chosen/stdout-path is a string, not ihandle. Treat it as such. With this, ofwfb now starts correctly on a POWER9 system when launched from the local console (not serial).
