The switch will be based on a configuration setting, i. e. you can change it only by changing the source code. You cannot for example compile the very same source code (without any changes to U-Boot source files) one time with and one time without using libgcc. > PATCH 2 for ARM only switch and do not use the libgcc anymore So it makes it not only the default, but actually the only supported setting (assuming you do not change the source code).

This does not change any of my arguments. I have made up my mind. I hereby reject patches 1 and 2 in their current form. To have the patches accepted for imainline, use of libgcc should be the common default setting for all architectures, and switching of the use of libgcc should be possible for any board and any architec- ture without having to change any file in the U-Boot source tree.
