The Beagleplay board uses two entirely separate builds to produce an image, rather than using an SPL build for this purpose.
JFTR, this is an incorrect explanation of what's going on. The TI K3 families have both a Cortex-R core and a Cortex-A core and the R core needs to come up before the A core. But in both cases we have U-Boot SPL and then U-Boot proper being used.
This is aside from having come back to re-review the series and still feel like this is taking the wrong approach to the problem. We wouldn't add a --optee-build-directory for going off and building OP-TEE and so forth. It's just the case that we need assorted binaries for the system and some of them come from building U-Boot for another platform.
