[U-Boot] Question about baud rate

[djantzen]

Hi,

I'm using a board similar to canyonlands with a ppc460ex. The baud rate 
for ttyS0 is set to 115200 by the console= bootarg, but I'd also like to 
set ttyS1-3 to 115200 also.

For each of the three uarts, the device tree has the following line:

current-speed = <0>; /* Filled in by U-Boot */

How do I go about configuring u-boot to fill these with the baud rate I 
choose?

Sorry for the silly question!

Thanks,
Dan
