Separate BSS is current mandatory on armv8 but this is not useful for early boot phases. Add support for the combined BSS. Use an #ifdef to avoid using CONFIG_SPL_BSS_START_ADDR which is not valid in this case. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>
