The method of multiplying a character by a number works well for creating a repeated string in Python 2. But in Python 3 we need to use bytes() instead, to avoid unicode problems, since 'bytes' is no-longer just an alias of 'str'. Create a function to handle this detail and call it from the relevant places in binman. Signed-off-by: Simon Glass <sjg@chromium.org>
