Hi,

Not really. This would be a new project to rewrite U-Boot driver for
OMAP3 DSS. There is a driver under drivers/video/omap3_dss.c,
but it doesn't do what we need here. You can try to set gdev.frameAdrs
to point to another address range in RAM which is not used by U-Boot.
Then get OMAP3430 TRM and read DSS documentation how to configure the
display controller so that is displays frame buffer data from this
address range. Currently I do not have time nor resources to rewrite
the existing omap3_dss driver.

Thanks,
Anatolij
