I tried building master (poky and meta-ti) with this patch, it does 
work, but needs change in u-boot-ti.inc (for do_install_append and 
do_deploy_append, changing ${S} references to ${B})

Git cloned ti-u-boot and used ti-u-boot-2016.05 branch

I added these in my local.conf

INHERIT += "externalsrc"
EXTERNALSRC_pn-u-boot-ti-staging = "/<path>/ti-u-boot"

Thanks
