From 064b55cfcb25c0f7692ecf6d4a38f12cd82739f7 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Wed, 14 Jun 2017 05:49:40 +0200 Subject: powerpc, 5xxx, 512x: remove support for mpc5xxx and mpc512x There was for long time no activity in the mpx5xxx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in mpc5xxx, so remove it.
