From 03449b84c8f9aee2bf2f438bec2c2ec4606bea48 Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Fri, 24 May 2013 18:02:35 +1000 Subject: dtc/fdt{get, put}/convert-dtsv0-lexer: convert to new usage helpers This helps standardize the flag processing and the usage screens. Only lightly tested; would be great if someone who uses these utils could double check.
