OP-TEE replace with different TEE

[LC1]

Hi,

Since Ecosystem 5 OP_TEE is mandatory.

We have previously used SP_MIN which is not supported anymore.

The change from SP_MIN to OP_TEE costs us approximately an extra second in boot time, we need to limit this as much as possible.

I came across in the wiki here - "STMicroelectronics provides OP-TEE support that also embeds a secure monitor on Armv7. It can be replaced with a trusted OS or another trusted environment execution (TEE).".

I was wondering, is it possible to change OP-TEE to a different lighter vendor? If so, is there a document describing the steps necessary?

Thanks in advance
