Why can't you put meta-ti in front of meta-yocto in Denzil? Works just fine.

Well, it's only the problem for the BBLAYERS order, so you don't really need 
any fancy setups, just do this in build/conf/bblayers.conf in Denzil:

  /OE/poky/meta \
  /OE/poky/meta-ti \
  /OE/poky/meta-yocto \

Or for Danny/master:

  /OE/poky/meta \
  /OE/poky/meta-yocto \
  /OE/poky/meta-ti \
  /OE/poky/meta-yocto-bsp \
