[CRYPTOMOUNT-TEST 3/7] grub-shell: Allow specifying non-default trim lin


From: Glenn Washburn
Subject: [CRYPTOMOUNT-TEST 3/7] grub-shell: Allow specifying non-default trim line contents.
Date: Sun, 16 Aug 2020 19:05:14 -0500

This will be useful for tests that have unwanted output from setup. This is
not documented because its only intended at the moment. Also, --no-trim is
allowed to explicitly turn off trim.
