From f432eb6d8a9d8a9382f6e7f0096fb4ee4672b8e8 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 11 Mar 2022 22:37:23 -0700 Subject: env: Avoid using a leftover text-environment file If include/generated/environment.h exists (perhaps leftover from a build of another board) it is used, even if the board currently being built does not have a text environment. This causes a build error. Fix it by emptying the file if it should not be there.
