Why you cannot use:
u-boot:drivers/video/da8xx-fb.c ?

Hi Heiko,
for my opinion this clone of the linux-driver is very overloaded and difficult
to use/configure.
With the words 'small-is-beautiful' and 'keep-it-simple' i've wrote a few lines
which do the minimum:
- configure raster-controller
- setup DMA
- powerON Display
maybe we can use the small-version in other projects too.
Why is it difficult to use/configure the existing driver?
Look for example into the board/siemens/pxm2/board.c board, which uses
this driver. You have to define:
static struct da8xx_panel lcd_panels[]
static const struct display_panel disp_panel
static const struct lcd_ctrl_config lcd_cfg
and call "da8xx_video_init(&lcd_panels[0], &lcd_cfg, lcd_cfg.bpp);"
Thats all ...
bye,
Heiko
