From 9a387128e341debb6d7e32df8e0f72669a3a079b Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 28 Jun 2016 10:48:42 +0900 Subject: linux/io.h: add generic ioremap()/iounmap() defines For most of architectures in U-Boot, virtual address is straight mapped to physical address. So, it makes sense to have generic defines of ioremap and friends in . All of them are just empty and will disappear at compile time, but they will be helpful to implement drivers which are counterparts of Linux ones. I notice MIPS already has its own implementation, so I added a Kconfig symbol CONFIG_HAVE_ARCH_IOREMAP which MIPS (and maybe Sandbox as well) can select.
