I figured this issue out, and it was something in the code file that I was
working with, though something I overlooked, not modified.

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.
I tried commenting out
#ifdef CFG_DEVICE_NULLDEV
memset (&dev, 0, sizeof (dev));
strcpy (dev.name, "nulldev");
dev.flags = DEV_FLAGS_OUTPUT | DEV_FLAGS_INPUT | DEV_FLAGS_SYSTEM;
dev.putc = nulldev_putc;
dev.puts = nulldev_puts;
dev.getc = nulldev_input;
dev.tstc = nulldev_input;
device_register (&dev);
#endif
in common/devices.c, as when CONFIG_SPLASH_SCREEN is defined,
CFG_DEVICE_NULLDEV gets defined, and would appear to reroute console output
once assigned with dev.putc = serial_putc would now be dev.putc =
nulldev_putc. However, this did not change the situation for me at all.
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.
Thanks,
