Thanks Tony. I checked the DTS/overlays using linux-yocto-4.1 kernel(Ostro OS). It seems to me that the kernel/u-boot do not include the latest overlay support patch. And I also tested the latest Debian 8.4 using BBB boards, the I2C1 does not work too. This patch is the simplest solution for I2C1/I2C2 in linux-yocto-4.1.

Probably best to wait on this one until we know how it can be enabled without manually editing the dts file. I'm still hoping u-boot could enable it based on some environment variable..
