[U-Boot] U-Boot: am335x video support

Hello,
is in current U-Boot a lcd driver for the am335x integrated LCD controller? If yes, also with Splash screen support?
Thanks!
bye, Heiko

Hi Heiko,
perhaps you should take a look at the DA8XX driver. At least under Linux this driver also handles the AM335x.
Splash screen support (meaning support of the splashimage variable) might be a problem because it expects a direct mapped physical address where the splash image is stored - typically some onboard nor flash. But AM335x designs typically have MMC, NAND or SPI flash attached. So you probably need some commands to load the spashscreen from a flash device and then use the 'bmp' command to display it. This should work with all video drivers.

Ah! Hmm... I found only one board, which uses this driver ... But it is a good starting point I think!
Thanks!
