From 593477c6b323030a0d46e8519b6e3f060b744639 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Thu, 14 Sep 2017 15:05:02 -0700 Subject: [PATCH] arc: Use asm-generic/io.h Convert the arc architecture to make use of the new asm-generic/io.h to provide address mapping functions. As the generic implementations are suitable for arc this is primarily a matter of removing code. Feedback from architecture maintainers is welcome.
