From abb9cd30b23858125ce015c1dffdae4d7895bae8 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 3 Oct 2020 11:31:26 -0600 Subject: dm: core: Allow dm_warn() to be used in SPL At present this option is disabled in SPL, meaning that warnings are not displayed. It is sometimes useful to see warnings in SPL for debugging purposes. Add a new Kconfig option to permit this.
