Put:

#define CONFIG_PREBOOT  "setenv stdout serial;setenv stdin serial"

in your board config file :-)

Than have a look at our linux-2.4 kernel tree; it make sLinux use the
same memory for framebuffer as used by U-Boot,  so  you  can  have  a
steady  image  from a few milliseconds after power-on until the Linux
GUI takes over :-) [Of course  you  can  also  load  "boot  progress"
screels in U-Boot using the "bmp" command...

Sure that would be helpful. I have only that many different boards in
our lab, and even stricter limits on available time :-(
