====== Compile U-Boot ======
Download and extract the archive with the patches. Then download the basic version using git.
<code bash>
user@ubuntu:/.../src$ git clone http://git.denx.de/u-boot.git u-boot
user@ubuntu:/.../src$ cd u-boot/
user@ubuntu:/.../src/u-boot$ git checkout -b v2010.06 a59e27997637a2395ae2cc7f809127f24119a167
user@ubuntu:/.../src/u-boot$ stg init
user@ubuntu:/.../src/u-boot$ stg import -t -s ~/source/uBoot/patches-tqma35_2010.06/series
</code>

The variables ''ARCH'' and ''CROSS_COMPILE'' have to be set accordingly.
<code bash>
user@ubuntu:/.../src/u-boot$ export ARCH=arm
user@ubuntu:/.../src/u-boot$ export CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.4.4-glibc-2.11.1-multilib-1.0/arm-fsl-linux-gnueabi/bin/arm-none-linux-gnueabi-
</code>
<WRAP round tip>
Both commads can also be added to ~/.bashrc or to the system wide configuration file ''/etc/bash.bashrc''.
</WRAP>

To configure and compile with ''make'' the following commands have to be executed:
<code bash>
user@ubuntu:/.../src/u-boot$ make distclean
user@ubuntu:/.../src/u-boot$ make TQMa35_config
user@ubuntu:/.../src/u-boot$ make all
</code>
