From 4d8b9909a22370209aa31cf1f3e49cb52060af06 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Tue, 26 Jul 2022 18:39:48 +0200 Subject: [PATCH] arch/Config.in.riscv: lp64f ABI is only supported if MMU is enabled Even though that seems weird, the LP64F ABI is only supported when MMU support is enabled. Indeed, as per commit 9a51381cedc16e6d70cb85e1144f6e0fa89af69a ("package/uclibc: prevent config with unsupported RISC-V float ABI"), uClibc does not support LP64F. But uClibc is the only C library that support RISC-V 64-bit noMMU. So the selection of LP64F and !MMU is impossible. Right now this selection causes a build failure as no C library is enabled. This commit fixes this by ensuring we cannot use LP64F when MMU support is not available.
