From 5b8e76c35ec312a3f73126bd1a2d2c0965b98a9f Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Wed, 7 Jun 2017 17:33:09 +0200 Subject: powerpc, 8xx: remove support for 8xx There was for long time no activity in the 8xx area. We need to go further and convert to Kconfig, but it turned out, nobody is interested anymore in 8xx, so remove it (with a heavy heart, knowing that I remove here the root of U-Boot).
