Fully linked apps take less storage and are efficient to load. This is to enable them for rv-vrit configurations in KERNEL build. Changes: - arch/risc-v/Kconfig select BINFMT_ELF_EXECUTABLE for QEMU-RV - boards/risc-v/qemu-rv/rv-virt/configs - knsh32/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST - knsh64/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST - ksmp64/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST - knetnsh64/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST - knetnsh64_smp/defconfig enable ELF_EXECUTABLE, LIBM, OSTEST Additions: - boards/risc-v/qemu-rv/rv-virt/scripts/ - gnu-elf.ld apps linker script The ARCH_TEXT_VBASE of knsh32 is set to same as that of 64bit to reuse the apps linker script.
