From d0d57a7460bf40f96818b064ca4cd9b687c58b4c Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Thu, 8 May 2014 20:04:02 -0700 Subject: nyan*: Add an empty elog functions for the !CONFIG_ELOG case Provide elog stub functions so eventlog support can be omitted without littering code with "#if CONFIG_ELOG". This makes it so coreboot can be built without eventlog support for these platforms for debugging purposes.
