From 8ac37b461c90987f02f011d17145f8d6ff484bc7 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Wed, 18 May 2022 12:54:01 +0200 Subject: [PATCH] riscv: remove CONFIG_ARCH_MAP_SYSMEM from io.h Commit ba1ed5b022c6 ("Convert CONFIG_ARCH_MAP_SYSMEM to Kconfig") clearly defined that this option is available for SANDBOX (was also for already removed NDS32). That's why there is no way how this code can be enabled with current Kconfig layout for riscv. Based on this removing this code.
