From 64e9b4f346f113dec984eaab226a44d35e38d7ce Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 4 Dec 2017 13:48:19 -0700 Subject: [PATCH] Revert "sandbox: Drop special case console code for sandbox" While sandbox works OK without the special-case code, it does result in console output being stored in the pre-console buffer while sandbox starts up. If there is a crash or a problem then there is no indication of what is going on. For ease of debugging it seems better to revert this change also. This reverts commit d8c6fb8cedbc35eee27730a7fa544e499b3c81cc.
