From 7793ac96c6094e0a0291e19a5bcf3000c6388250 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 23 Jul 2014 06:55:06 -0600 Subject: console: Remove vprintf() optimisation for sandbox If the console is not present, we try to reduce overhead by stopping any output in vprintf(), before it gets to putc(). This is of dubious merit in general, but in the case of sandbox it is incorrect since we have a fallback console which reports errors very early in U-Boot. If this is defeated U-Boot can hang or exit with no indication of what is wrong. Remove the optimisation for sandbox.
