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. Signed-off-by: Aleksander Jan Bajkowski <olek2@wp.pl> |

This Malta target is intended to be used with the Qemu emulator. It can be used to prototype an OpenWrt firmware for MIPS processors. One could also use it to troubleshoot MIPS applications without access to real hardware. To use the images built by OpenWrt with qemu, use the following commands: For the 32 bit little-endian image: qemu-system-mipsel -kernel bin/targets/malta/le/openwrt-malta-le-vmlinux-initramfs.elf -nographic -m 256 For the 32 bit big-endian image: qemu-system-mips -kernel bin/targets/malta/be/openwrt-malta-be-vmlinux-initramfs.elf -nographic -m 256 For the 64 bit little-endian image: qemu-system-mips64el -kernel bin/targets/malta/le64/openwrt-malta-le64-vmlinux-initramfs.elf -cpu MIPS64R2-generic -nographic -m 256 For the 64 bit big-endian image: qemu-system-mips64 -kernel bin/targets/malta/be64/openwrt-malta-be64-vmlinux-initramfs.elf -cpu MIPS64R2-generic -nographic -m 256 and enjoy the system bootin.
