From 891f7ae63318293cd5807fb611f86f545080b1f6 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 2 Apr 2017 09:50:32 -0600 Subject: [PATCH] dm: serial: Allow driver-model serial to be disabled for TPL Add separate enable/disable controls for driver-model serial. While this is generally enabled in SPL it may not be in TPL, since serial output can be obtained with the debug UART with minimal code size.
