Linaro 14.04 Release with Linux Kernel 3.14 and Android 4.4.2

Linaro 14.04 has been released with Linux Kernel 3.14 (baseline), Linux Kernel 3.10.37 (LSK), and Android 4.4.2.

More work has been done on ARMv8 support, and big.LITTLE for both the Linux kernel and Android, as well as work on member hardware platforms such as Origen, Arndale, Arndale Octa, Broadcom Capri, and Hisilicon D01 boards. GCC 4.8-2014.04 Linaro is said to include performance improvements. Linaro Android engineering builds for Nexus 7 and Nexus 10 have been setup, but I can’t quite find the images. They’ve also added the BeagleBone Black to member builds.
