The sandbox should closely mimic other architectures. Place each function or data in a separate section and let the linker eliminate unused ones. This will reduce the binary size. In the linker script mark that u_boot_sandbox_getopt are to be kept. Signed-off-by: Heinrich Schuchardt <heinrich.schuchardt@canonical.com> Reviewed-by: Tom Rini <trini@konsulko.com>
