Configure U-Boot

First you need to chose a correct defconfig for your board;

When you have determined what <board_name> you want to build, configure:

make CROSS_COMPILE=arm-linux-gnueabi- <board_name>_defconfig

You may need to change the U-Boot function/feature support by modify the defconfig file or,

there is also menuconfig to play with settings if you feel like it:

make CROSS_COMPILE=arm-linux-gnueabi- menuconfig

Build U-Boot

Get a toolchain

If you haven't done so before, get a suitable toolchain installed and added to your PATH.
