SuperH is supposed to support the Private Library feature, but it is actually not working. If CONFIG_USE_PRIVATE_LIBGCC is enabled, the build fails for the undefined references to '__sdivsi3_i4i' and '__udivsi3_i4i'. To fix this error, import missing libraries from Linux 3.19 and adjust them for U-Boot: - Remove "#include <linux/module.h>" and "EXPORT_SYMBOL(...)" - Use SPDX-License-Identifier - Remove white space Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Nobuhiro Iwamatsu <iwamatsu@nigauri.org>
