From 680e3c6edb9aa5cf400a5b22ecfa3a40b0b247e5 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 26 Oct 2020 17:40:02 -0600 Subject: [PATCH] binman: Give a sensible error if no command is given At present if 'binman' is typed on the command line, a strange error about a missing argument is displayed. Fix this. These does not seem to be standard way to add the 'required' argument in all recent Python versions, so set it manually.
