At present cli_simple_process_macros() requires that the caller provide an output buffer that is exactly CONFIG_SYS_CBSIZE bytes in length. This makes sense since it is designed to be used from the command line. But we also want to use it for bootargs substitution. Update the function to allow the caller to specify the buffer size. Also return an error if the buffer is exhausted. The caller can ignore that if preferred. Signed-off-by:Simon Glass <sjg@chromium.org>
