From 46ca3a55344b326553358b5119cb8a342a493ed4 Mon Sep 17 00:00:00 2001 From: Alexander Couzens Date: Sat, 7 Feb 2015 04:10:12 +0100 Subject: ectool: add --dump / -d for RAM dump This moves the ram dump behind an argument, but it's still called by default when no other arguments given. To hold backward compatibility -i also prints out RAM.
