Secure SPI : STM32MP157-DK1 board

Hey everyone,

I am working on STM32MP157-DK1 with trustzone cortex-A.
I want to use the SPI in secure side, but it's possible only with SPI 6 that is not mapped to the outside.

It's possible to activate SPI (1 ... 5) peripherals in secure side ? if not, why ?

Best regards
