IMX8M and Optee support

Just reaching out to ask whether anyone has successfully integrated Optee on the IMX8M(P) platform.
Our trials results in a crash when the ATF (NXP 2.8) does the handover to Optee (exit EL3).

In ATF it appears that BL32 is expected to load at 0x56000000 on IMX8MP while Barebox actually loads
The Optee bin blob just below top of memory.
(Patching Barebox to the expected ATF BL32_BASE does not resolve the issue)

Any help would be appreciated
