Linaro release 12.08 includes Linux Kernel 3.6-rc2 and is the very first release with Android Jelly Bean (4.1.1-R4).
The Android platform team has managed to port Android Jelly Bean to all their main development platforms: Versatile Express, Versatile Express RTSM, Samsung Origen, TI PandaBoard, ST Ericsson Snowball, as well as Samsung Galaxy Nexus smartphone. They’ve also added TINY_ANDROID, a minimal Android build that can be used for kernel development, toolchain work and other development where users only need a console. It’s possible to get the source code, build it and access the shell within 10 minutes. U-boot-Linaro has been updated and is now based on the latest upstream release v2012.07.
Next month, we might be able to see a preliminary port of Android on 64-bit platform (ARMv8).
Here are the highlights of the release:
