The boards are different form factors. Since the hardware layout is 
different there are some board specific imx6 register settings needed 
(eg: usb phy settings, pcie gpr8 settings etc.).  We are in the process 
of submitting imx driver patches for the same and expect the 
imx6q-b450v3.dts and imx6q-b650v3.dts to be different in the near 
future. Hence would like to keep them separate.
