Hi everyone,

When adding support for new platform we ran into an issue with BL2 variable.

In our architecture we have Bootloader based on MCUboot (aka BL2) but we are not planning to build it with TF-M.

Bootloader would be separate repo and be built separately.

So we need the way to build TF-M with FWU service and shared data definitions when BL2=OFF.

I was trying to add support for this but was not able to do this because build structure is quite complicated.

Does anyone have ideas or suggestions about the way we can implement this feature?

Best regards,
