Subject: [PATCH 4/13] au1100fb: Fix startup sequence
Date: Tue, 01 Aug 2006 07:27:03 +0800 [thread overview]
Message-ID: <44CE91C7.5070807@gmail.com> (raw)
From: Rodolfo Giometti <giometti@linux.it>
- fix up the start up sequence.
This new sequence allow you to correctly enable the LCD controller
even if the bootloader has already did it.
- fix up a wrong indentation issue.
