From 36bcea62af98145e6859cabec9c8f82d1d057bf9 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 15 Nov 2018 18:44:04 -0700 Subject: [PATCH] sandbox: Allow puts() output before global_data is set up We support putc() in this case but not puts(), but this is more useful since it is what printf() uses. This particularly affects debugging early in SPL, where currently printf() statements result in no output. Fix this by adding a special case into puts() for sandbox, just like putc().
