u-boot files - device specific?

[Aditya Kousik]

Hi Ivan,

Turns out that the board we use already has u-boot. Do we still need to get
a working copy u-boot? I added SPECS += uboot to the etc/specs.conf file.
Ran make run/demo again. I now have image.elf and uImage. What's the next
step from here? Just use dd command in terminal and copy the uImage to SD
card?

What other u-boot arguments need to tweaked here?

Aditya
