From 505fe9cdd0e9613ee1f081b58d2fb69bdf1c1eae Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Thu, 14 Sep 2017 15:05:07 -0700 Subject: [PATCH] sh: Use asm-generic/io.h Convert the sh architecture to make use of the new asm-generic/io.h to provide address mapping functions. As the generic implementations are suitable for sh this is primarily a matter of moving code. Feedback from architecture maintainers is welcome.
