From 0884077b70b0c1373be90e7221b6780aa6756563 Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Thu, 14 Sep 2017 15:05:04 -0700 Subject: [PATCH] m68k: Use asm-generic/io.h Convert the m68k architecture to make use of the new asm-generic/io.h to provide address mapping functions. As the generic implementations are suitable for m68k this is primarily a matter of emoving code. Feedback from architecture maintainers is welcome.
