With Himba"s help, I got things running much better for my OMAP 1510 Innovator LCD driver U-Boot, but once the LCD comes up (drv_lcd_init finishes), the serial console output is switched off. I can still issue

commands from my serial console, and have them take effect (like changing a status LCD or turning off the LCD backlight with mm.b), but can"t see any more text output.
You should see it on the LCD now.
I tried commenting out
#ifdef CFG_DEVICE_NULLDEV
Don't do this.
Any ideas on how to maintain the serial terminal? Take note that my driver is very very similar to cpu/mpc8xx/lcd.c, so I do not expect that coding that I did is disabling the serial terminal, but instead some other interaction in the code is doing this.
The normal mode of operation is that when there is a LCD then the console output goes to the LCD by default. You can always change this by assigning a different device to the stdout / stderr descriptors. Either interactively by entering (probably blind) a "setend stdout serial" command, or you can put this command in your CONFIG_PREBOOT setting.
