From efb0b51e62667ade4d96f2a15eb6ed60bb29a9fe Mon Sep 17 00:00:00 2001 From: Kyösti Mälkki Date: Sun, 13 Apr 2014 17:57:34 +0300 Subject: console: Split ROMCC helpers MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit These are potentially useful with GDB or SerialICE too. Also it reduces the amount of actual code we put in romcc_console.
