As mentioned in our previous post about Linux kernel 3.5.7, Freescale has released an alpha version of an i.MX kernel based on 3.10.9.

We've taken a first pass at testing this out and adding support for Nitrogen6X into this tree and merged the results into branch boundary-imx_3.10.9_1.0.0_alpha on Github.

The test results are in the list below, and a substantial set of functionality is present.

Our intent at the moment is to perform a similar first-pass review of main-line Linux next before adding any additional support to the 3.10.9 tree.

The delta between these two is shrinking fast, and we'll be making an effort to push our changes up-stream from this point forward.

We'll also push updates to the meta-freescale list to make it easier for Yocto users to test things out.
