From e8645527b1c2f6d56fef04bc43d1e81ae1904fae Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Thu, 14 Sep 2017 15:05:09 -0700 Subject: [PATCH] xtensa: Use asm-generic/io.h Convert the xtensa architecture to make use of the new asm-generic/io.h to provide address mapping functions. As the generic implementations are suitable for xtensa this is primarily a matter of moving code. This has only been build-tested, feedback from architecture maintainers is welcome.
