OK.  But, automatic how?  What I'm getting at, from both a documentation
standpoint and also how I run my labs standpoint, is that it seems like
instead of having a set of TF-A and OP-TEE binaries for each TI K3
platform I have, I really need just 3 different TF-A builds (well, in
reality I don't have the J784s4 stuff so just 2) and a single OP-TEE
build.
