Linaro 13.02 Release with Linux Kernel 3.8 and Android 4.2.2

Linaro 13.02 is now available, and features Linux Kernel 3.8 and Android 4.2.2.

The biggest news this month is probably the first release of a preliminary ARM64 Debian/Ubuntu Raring image. Other noticeable items include work on ARMv7 KVM, more improvements to OpenEmbedded ARMv8 implementation, as well as big.LITTLE MP implementation, and some modifications to the toolchain for Cortex A7 support. Origen images are not available for download this month, and there’s still no ALIP images since they have disappeared since Linaro upgraded to Ubuntu Quantal.
