Linaro 14.02 Release with Linux Kernel 3.14 and Android 4.4.2

Linaro 14.02 has just been released with Linux Kernel 3.14-rc3 (baseline), Linux Kernel 3.10.30 (LSK), and Android 4.4.2 r2.

There are been a lot of patches for Linaro members boards, and including the latest GTS big.LITTLE processing patch, as well as speeds up to Android 4.4 performance. There’s also a Linux image (password protected) for Huawei D01 board with a 16-core ARM Cortex A15 @ 1.5 GHz SoC with up to 64 GB memory, that must be an unannounced SoC for base stations or other network equipment.  This month Linaro also made two important announcements: Qualcomm is now a Linaro member, and the Linaro Security Working Group (SWG) has been setup to develop open source secure software for the ARM architecture. The first projects will be reference implementations of the W3C Embedded Media Extension (EME), and secure boot for the 64-bit ARM Cortex-A series processors. They’ll also work on security for the Linux kernel.
