From 40a6c00f58ef138ea2c009792c65ad31ab627be5 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 7 Mar 2018 14:29:23 +0100 Subject: ARM: ux500: Drop U8540/9540 support The U8540 was an evolved version of the U8500, but it was never mass produced or put into products, only reference designs exist. The upstream support was never completed and it is unlikely that this will happen so drop the support for now to simplify maintenance of the U8500.
