From bf1457bdbb736a54eb2eb70bc531e11eb468de7e Mon Sep 17 00:00:00 2001 From: Thomas Huth Date: Fri, 1 Sep 2017 09:38:12 +0200 Subject: target/ppc: Remove old STATUS file The target/ppc/STATUS file has seen its last real update 10 years ago - so the information in there is not up to date anymore. Since nobody seems to care about this file, let's simply remove it.
