From 47c5455a489c8e558ecb002a3a97a030ce490f9e Mon Sep 17 00:00:00 2001 From: Helmut Raiger Date: Thu, 29 Sep 2011 05:45:03 +0000 Subject: mx31: provide readable WEIM CS accessor setup_weimcs() and some macros are added to support the setup for i.MX31 WEIM chip selects. As a compromise between verbosity and readability an ASCII-art'ish bit comment is used instead of bitfields. All i.MX31 boards have been patched to use this approach using a helper program to verify the changes.
