From 8f8e6304df54b36d5971a69ff3de0f6f9ad4bf4e Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Thu, 14 Sep 2017 15:05:03 -0700 Subject: [PATCH] arm: Use asm-generic/io.h Convert the arm architecture to make use of the new asm-generic/io.h to provide address mapping functions. As the generic implementations are suitable for arm this is primarily a matter of removing code. This has only been build-tested, feedback from architecture maintainers is welcome.
