Subject: [PATCH] au1100fb.c startup sequence
Date: Wed, 12 Jul 2006 09:02:21 +0200	[thread overview]
Message-ID: <20060712070221.GI5994@gundam.enneenne.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 551 bytes --]

Hello,

here a patch to 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.

The patch also fixes up a wrong indentation issue.

Ciao,

Rodolfo
