From dc9f5cd54661e5ba3fffee7af0ba17dde9367b95 Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 8 Sep 2015 13:34:43 -0500 Subject: coreboot: introduce commonlib Instead of reaching into src/include and re-writing code allow for cleaner code sharing within coreboot and its utilities. The additional thing needed at this point is for the utilities to provide a printk() declaration within a file. That way code which uses printk() can than be mapped properly to verbosity of utility parameters.
