From d3716dd64bb8bb4c4ba2d19bac164d24ada72a68 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 1 Aug 2019 09:47:08 -0600 Subject: env: Rename the redundancy flags Add an ENV prefix to these two flags so that it is clear what they relate to. Also move them to env.h since they are part of the public API. Use an enum rather than a #define to tie them together.
