Hello,

I'm following up on the RFC I sent in January [1] about moving OP-TEE
support from meta-arm to oe-core.                                     
   
Thank you to everyone who participated in the discussion, Ross, Khem,
Sumit, Rahul and John.                                                
                  
OP-TEE is being adopted on RISC-V (non-ARM) platforms, and having it in
oe-core would avoid duplication and fragmentation across layers,
consolidate generic parts, and make it accessible without a dependency
on the ARM BSP layer. This follows the same model as U-Boot, which was
seen as a valid precedent.

Please let us know if you have any remaining concerns or objections,
then to move forward and maybe prepare a first patch series adding OP-
TEE recipes to oe-core with support for qemuarm64 and qemuriscv64 as a
first step.

Kind Regards,
Thomas Perrot
