Android git kernel trees

As of July 2010, the android repository on kernel.org had the following kernel trees:

kernel/common.git 

This is the kernel tree that matches what is put into official Android products by Google or its partners

kernel/experimental.git 

some experimental stuff

kernel/linux-2.6.git 

mirror of Linus' kernel tree. This is a reference for the kernel tree used in Android

kernel/lk.git 

not a kernel tree, but a bootloader

kernel/msm.git 

kernel for MSM (Qualcomm chip used in many HTC products)

kernel/omap.git 

mirror of kernel tree maintained by texas instruments., supporting OMAP chips. usually based on kernel.org latest version, android products w OMAP chip can use this kernel port.

kernel/tegra.git 

nvidia kernel tree
