From 580fa2bf316d4796e5ed76cbbd3e454479fb0688 Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Wed, 6 Feb 2013 21:51:15 +0800 Subject: console: Only print romstage messages with EARLY_CONSOLE enabled. Revise console source file dependency (especially for EARLY_CONSOLE) and interpret printk/console_init according to EARLY_CONSOLE setting (no-ops if EARLY_CONSOLE is not defined). Verified to boot on x86/qemu and armv7/snow. Disabling EARLY_CONSOLE correctly stops romstage messages on x86/qemu (armv7/snow needs more changes to work).
