The patch titled
s3c2410fb: byte ordering fixes
has been removed from the -mm tree. Its filename was
s3c2410fb-byte-ordering-fixes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: s3c2410fb: byte ordering fixes
From: Krzysztof Helt <krzysztof.h1@xxxxx>
This patch sets correct bits related to the byte ordering of the
framebuffer. This was tested on little endian kernel only. The big endian
kernel may require different settings.
The patch also adds 32 bpp mode which is called 24 bpp by Samsung. One
pixel takes 32 bits but only 24 bits are used in this mode.
