From a5fe13c7b49478c95e74f31f5b8b8347735684a7 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Mon, 13 Apr 2020 18:04:49 +0900 Subject: [PATCH] riscv: select ARCH_HAS_STRICT_KERNEL_RWX only if MMU ARCH_HAS_STRICT_KERNEL_RWX is not useful for NO-MMU systems. Furthermore, has this option leads to very large boot image files on 64bits architectures, do not enable this option to allow supporting no-mmu platforms such as the Kendryte K210 SoC based boards.
