From 3e3f354bc383a052cde431d8f051efbf896f260b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 24 Sep 2020 20:25:46 +0200 Subject: ARM: remove ebsa110 platform Russell said that he is no longer using this machine, and it seems that nobody else has in a long time, so it's time to say goodbye to it. As this is the last platform using CONFIG_ARCH_USES_GETTIMEOFFSET, there are some follow-up patches to remove that as well.
