git clone git://git.goldelico.com/letux-uboot.git
cd gta04-uboot

Build (for GTA04)

export ARCH=arm
export CROSS_COMPILE=arm-linux-gnueabi-  # adapt to your toolchain

make letux_gta04_defconfig

The result will be the file u-boot/MLO. Copy this file to the FAT partition of your SD card. This has to be the first file on the FAT partition. To achieve this, you either have to create a fresh FAT partition and copy the MLO file as the first file to it or later replace this first-copied file with a more current version.

Build (for Openmoko Beagle Hybrid)

make omap3_beagle_defconfig

Build (for OMAP5 Pyra)

make pyra_defconfig
