How to port zephyr for new socs?

Question

I am new to zephyr and I would like to port it for other socs that it currently does not support, like many in the stm32 series. I could not find any guide in the zephyr documentation to port it to new socs. While there is a guide for architecture porting. There seems to be no official document to port it for a new soc.

I would be glad to receive any pointers that would help me.

A little late, but zephyr supports stm32 now:
