[directfb-dev] CLE266 DFB driver v0.2 released



Hi guys,

I have released version 0.2 of my CLE266 driver. Besides having a video
overlay layer, it can now handle all VRAM->VRAM drawing and blitting
functions for RGB surfaces, except colorkeyed stretch blits. There doesn't
seem to be a good way to do color keying with the 3D controller....

I still consider the driver to be in the alpha stage, because some key parts
are missing (eg VBI wait), and some functions run slower than they did on
earlier versions, but it seems to handle the DirectFB test programs well on
my EPIA-M10k.

Please download and be mean to it. :-)

Notes:

All blits use a modified df_dok which blits from video RAM.
The numbers for software rendering are taken from an unmodified df_dok
since software rendering in video RAM is Very Slow.

Operations marked with an S are performed by the software renderer.
Operations marked with an asterisk (*) could use some optimization.

v0.0.1 and v0.1.0 are tested on an EPIA-M9000,
v0.2.0 is tested on an EPIA-M10000
