From 294b91a5817147d4b7f47be2ac69bac2a1f26491 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Wed, 3 Sep 2014 17:37:00 -0600 Subject: Set up stdio earlier when using driver model Since driver model registers itself with the stdio subsystem, and we want to avoid delayed registration and other complexity associated with the current serial console, move the stdio subsystem init earlier when driver model is used for serial. This simplifies the implementation. Should there be any problems with this approach they can be dealt with as boards are converted over to use driver model for serial.

Adjust the board init to arrange this, but enable it for driver model only, just to be safe. This does create additional #ifdef logic, but it is safer than trying to make a pervasive change which may cause some boards to break.
