From adba04e53f934fda623c7c1ef180653c7d907b2b Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Fri, 19 Jul 2013 17:12:44 +0000 Subject: procd: improve early console handling The malta target is broken since procd is used as init. The initramfs image boots fine, however the console is not working. Improve the early console handling to fix the problem.
