From 84d46e7e8948780d7ca20c24dfc7b653b900f728 Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Thu, 26 Oct 2017 14:57:53 +0200 Subject: [PATCH] tools: env: allow to print U-Boot version The fw_env utility family has a default environment compiled in which ties it quite strongly to the U-Boot source/config it has been built with. Allow to display the U-Boot version it has been built with using the -v/--version argument.
