Over the last two years, the ARM support in the kernel has considerably evolved: usage of the Device Tree, introduction of the pinctrl and clock frameworks, introduction of multiplatform support, new code organization, and more.

Based on the speaker's experience of getting the support for the new Armada 370 and Armada XP ARM processors from Marvell into the mainline Linux kernel, this talk will detail the most important steps involved in this effort, and through this, give an overview of those changes and summarize the new rules for ARM Linux support.

This talk will be useful to both developers willing to add Linux support for a new SoC, but also to the developers willing to better understand the ARM code base in order to port Linux to a new hardware platform.

The Qt framework is best known by most developers as a graphical toolkit library, which allows to build graphical interfaces with windows, buttons, checkboxes and drop-down lists. However, Qt is not limited to graphical application development and through this talk, we would like to highlight the multiple features that Qt offers to embedded Linux developers developping non-graphical applications. Based on the experience of a real non-graphical application developped for a customer, we will detail how Qt has helped integrating features such as communication with multiple devices over serial ports, communication with a GSM modem, XML parsing, HTTP requests, communication with Linux input devices, and more.
