Build U-Boot
------------
Device support is implemented by applying a config fragment to a generic board
defconfig. Valid fragments are ``tf201.config``, ``tf300t.config``,
``tf300tg.config``, ``tf300tl.config``, ``tf700t.config``, ``tf600t.config`` and
``p1801-t.config``.
U-Boot features ability to detect transformer device model on which it is
loaded. The list of supported devices include:
- ASUS Transformer Prime TF201
- ASUS Transformer Pad (3G/LTE) TF300T/TG/TL
- ASUS Transformer Infinity TF700T
- ASUS Portable AiO P1801-T
- ASUS VivoTab RT TF600T
.. code-block:: bash
$ export CROSS_COMPILE=arm-linux-gnueabi-
$ make transformer_t30_defconfig tf201.config # For TF201
$ make transformer_t30_defconfig
$ make
After the build succeeds, you will obtain the final ``u-boot-dtb-tegra.bin``
