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. -- Tom
