Author: andrew Date: Sat Apr 11 17:52:47 2015 New Revision: 281439 URL: https://svnweb.freebsd.org/changeset/base/281439 Log: Add support for the QEMU virt SoC. This is a SoC built depending on the command line arguments passed in. It will then generate a dtb on the fly, as such no dts will be added as it may be incorrect.
