[meta-freescale] Build image for more devices beyond IMX6 EVK

[JH]

Hi,

I was working and building images on iMX6 EVK using
https://github.com/Freescale/meta-freescale, I am going to build an
image for a product using i.MX-6ULZ MCU, there are extra devices such
as Flash, real time clock etc.

My understanding, there are two things I might need do for building
the new hardware:

- Replace iMX6 EVK device tree by new hardware device tree (that will
be in meta-linux).
- Do I need to add / extend BSP recites for Flash, real time clock
etc? Or the current https://github.com/Freescale/meta-freescale has
already included everything?

Thank you.

Kind regards,
