From 85d993cef9b8e16431800dfc23e90e23bb144357 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Beno=C3=AEt=20Th=C3=A9baudeau?= Date: Mon, 20 Aug 2012 09:00:57 +0000 Subject: mx25: Clean up lowlevel_init MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Clean up mx25 lowlevel_init: - Add comments. - Do not use write32 repeatedly with the same value in order not to increase code size. - Make register values configurable. - Use macro parameters with default values instead of literal constants. - Use defined macros instead of duplicating code.
