Port U-Boot, Linux to T4240 systems

This document covers the main areas within the U-Boot and Linux sources that a developer should be aware of to port these packages to a new T4240 platform. It also assumes the reader has at least a basic knowledge on U-Boot, Linux and git. Note that the code sources referenced in this document are based on SDK 1.4 which uses U-Boot 2013.01 and Linux kernel 3.8.13. For different U-Boot or kernel releases there may be slight changes to some of these references.

The SDK includes support for the T4240QDS, therefore T4240 device support is already included within the package. As such, the items discussed here focus on board level changes. For the purposes of this document, the example platform is the T4240-SDP, a custom T4240 reference design from Freescale.
