Code review comment for lp:~mabac/linaro-image-tools/snowball-support

"Move functions install_snowball_boot_loader, create_toc and get_file_info into SnowballImageConfig since they are specific to Snowball."
Did you rerun the unit tests after this? I had to move these functions to a global scope when adding unit tests, as otherwise the test framework would not stub them, and they would try to install non-existing files.
