From 7538ec7d1e5990f719538aeec9c021ba694040d9 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Tue, 21 Oct 2014 14:16:54 +0200 Subject: ARM: at91: remove no-MMU at91x40 support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As there is currently no-one to take care of this old !MMU target and as its support in recent kernels is a bit rotten, remove this at91x40 support and the board file associated with it (at91eb01). There are modern ARM !MMU in Mainline now so this target is not interesting for building tests anymore. It would be better to start from these modern ARM !MMU platforms to reintroduce at91x40 support if needed.
