From c3a09ff68ddffd1efd57612706484aa386826518 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Sun, 26 Apr 2020 12:16:37 +0200 Subject: hw/mips/fuloong2e: Fix typo in Fuloong machine name MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We always miswrote the Fuloong machine... Fix its name. Add an machine alias to the previous name for backward compatibility.
