Hi,
=> if OPTEE is loaded after SPL the U-Boot configuration change (running

I am starting to work on these issues in the branch
https://github.com/u-boot/u-boot/compare/master...patrickdelaunay:spl_optee_W2140
https://github.com/u-boot/u-boot/commit/04ad553e9c6bee62781460d2952df4962e58ae14

But it is still not working, OP-TEE is not correctly started
