In-Reply-To: <20210707175950.eceddb86c6c555555d4730e2@linux-foundation.org>

From: Mike Rapoport <rppt@linux.ibm.com>
Subject: riscv/Kconfig: make direct map manipulation options depend on MMU

ARCH_HAS_SET_DIRECT_MAP and ARCH_HAS_SET_MEMORY configuration options have
no meaning when CONFIG_MMU is disabled and there is no point to enable
them for the nommu case.

Add an explicit dependency on MMU for these options.
