From 9226f1e41948e841c1a546a6b58273e6e994539a Mon Sep 17 00:00:00 2001 From: Aleksander Jan Bajkowski Date: Mon, 22 Feb 2021 19:48:42 +0100 Subject: kernel: disable CONFIG_CPU_LITTLE_ENDIAN in generic config Endianness depends on CPU architecture. CONFIG_CPU_(BIG/LITTLE)_ENDIAN should be enabled on target or subtarget based on SoC architecture. Fixes warning: $ make kernel_oldconfig CONFIG_TARGET=subtarget ... .config:1008:warning: override: CPU_LITTLE_ENDIAN changes choice state .... Summary: - ARC - only the CONFIG_CPU_BIG_ENDIAN symbol is defined for this architeture. If it is disabled then the processor operates in LITTLE_ENDIAN mode (default), - ARM32 - CONFIG_CPU_LITTLE_ENDIAN symbol available since kernel 5.19. This option should be enabled after OpenWRT moves to kernel 6.x. After refreshing the kernel, the symbol disappears, - ARM64 - enabled CONFIG_CPU_LITTLE_ENDIAN, - MIPS - enabled relevant symbols, - POWERPC - enabled CONFIG_CPU_BIG_ENDIAN, - UML - Symbols are not defined for this architecture, - X86 - always little endian. Symbols are not defined for this architecture.
