From 91b136c7989e763b01632ca3de6fca8ead0b847b Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 10 Nov 2013 10:27:01 -0700 Subject: sandbox: Allow the console to work earlier With sandbox, errors and problems may be reported before console_init_f() is executed. For example, an argument may not parse correctly or U-Boot may panic(). At present this output is swallowed so there is no indication what is going wrong. Adjust the console to deal with a very early sandbox setup, by detecting that there is no global_data yet, and calling os functions in that case.
