The Linaro team ported the Chromium Embedded Framework to Linux running on ARM, the framework utilizes an EGL backend integrated using Chromium's Ozone abstraction layer.
ST’s latest ARM Powered System-on-Chips supporting Android, Google TV (now Android TV), rdk, ST presents their STiH312 client-box and STiH412 server-box product families, codenamed ‘Cannes’ and ‘Monaco,’ respectively, they integrate Faroudja technology to decode and display video up to Ultra HD 4K (2160p) and the next-generation H.265 / HEVC video compression. Even supporting video transcoding (for local and remote streaming from the Set-top-box to Tablets, Smartphones, etc) STMicroelectronics presents their Dual core ARM Cortex-A9 (on 28nm process) with quad-core Mali-400 GPU does Quad-HD Ultra HD 4K HEVC video decoding, combined with Faroudja video processing technology (decoding on Cannes, decoding and transcoding on Monaco), advanced security supporting concurrent conditional access and DRM, wide connectivity, including USB 3.0, PCI-e, SATA and Gigabit Ethernet, Dedicated interfaces to a range of companion front-end solutions, including MoCA 2.0, DOCSIS 3.0, satellite and 802.11ac WiFi and more.
Linaro Security Working Group (SWG), Jens Wiklander, Joakim Bech, Pascal Brand and Cedric Chaumont are talking about what is happening within Linaro's working group that handles security. The group is currently focusing on creating an open source Trusted Execution Environment (TEE) solution running on TrustZone® for ARMv7 and ARMv8 architecture. They also mention that they are going to work on secure boot (UEFI) and DRM schemes (EME) later on. According to SWG there has been and is a lot of interest shown from various companies, markets and countries. People have a hard time trusting a black box that is supposed to protect their most valuable assets. Therefore it is more than welcome to create an open source TEE solution right now, says SWG.
The Unbound Robotics UBR 1 is a robot that uses a combination of both ARM Cortex and x86 processors. The UBR 1 is designed as a platform for robotics development and uses ROS (robotics operating system) which is open source. The main processor currently in the robot is an x86 but it uses 12 ST Microelectronics ARM Cortex-M4 based microcontrollers to control each part of the robot.

ST is the current leader in ARM Cortex-M series shipments, those microprocessors go into everything.
