From 1b05d887d702fcf5ac704d2ee5257122a180694c Mon Sep 17 00:00:00 2001 From: Daisuke Nojiri Date: Wed, 27 Aug 2014 11:48:03 -0700 Subject: nyans: reduce code duplication in bootblock and romstages this change reduces the code duplication of the bootblock and the romstages for Nyans. BUG=none TEST=Built Nyan, Big, and Blaze. Ran faft on Blaze.
