Author: adrian Date: Thu Oct 22 08:08:06 2015 New Revision: 289745 URL: https://svnweb.freebsd.org/changeset/base/289745
Log: Add support for the TP-Link TL-WR740N v4. This is an AR9331 part based on the AP121 reference design but with 32MB RAM. Yes, it has 4MB flash and it has no USB, so clever hacks are required to get it up and working. But boot/work it does.
