[U-Boot] Question: Frescale imx board repositories

Hello all,

I'd like to know what's the difference between the Frescale imx board repositories from:

1) https://source.codeaurora.org/external/imx/uboot-imx 2) https://github.com/Freescale/u-boot-fslc

It seems that #2 is rebased more often and is referenced by yocto. I was wordering if the differece could be in stability or board support.

Thanks for your help, Fernando
