From ca27ac4cc6caa73740122a5f3d601c8a27b89e7c Mon Sep 17 00:00:00 2001 From: Rodolfo Giometti Date: Tue, 3 Oct 2006 01:14:36 -0700 Subject: [PATCH] au1100fb: Add option to enable/disable the cursor - add cursor enable/disable, very useful if you wish a full screen boot logo. Cursor can be disabled from kernel command line: video=au1100fb:nocursor,panel:Toppoly_TD035STED4 or from sysfs interface: echo 1 > /sys/module/au1100fb/parameters/nocursor - fix up some wrong indentation issues.
