iMX8MM support for HAB and encrypted image in the mainline

[Mircea Ciocan]

Hello everybody,

I have a board with iMX8MM that needs to have HAB and encryption of the 
U-Boot and kernel image active. OP-TEE is a nice to have, but no hard 
requirement and there is absolutely no need for any multimedia features 
(for all is needed the related blocks cold remain "dark").

I knew of course of the NXP fork used allover, that is mutilated beyond 
recognition IMHO, but I was wondering if the above needed features are 
supported in the mainline and if there is even a scrap of 
documentation/tutorial regarding implementing this on the mainlime.


  Thanks and best regards,

  Mircea
