From 3775dcd9c4ad9d7f19f2ff14989f5180aaba3d64 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Tue, 4 Mar 2014 15:52:35 -0500 Subject: [PATCH] cmd_nvedit: Make 'env import -c' require size parameter When importing a checksummed area we need to be told how big the area in question is so that we know that will match the size of the area which the checksum is generated against.
