[TF-A] Purpose of ENABLE_PIE in TF-A without ASLR

Hello,

I'm trying to understand the purpose of ENABLE_PIE build flag.

IIUC, it makes the BL* executables position-independent. But I could not find any ASLR or some other addresses randomization support. Therefore, could you please clarify, what is the point of building position-independent parts, if (most of the time?) they will be loaded at the fixed addresses?

Thank you.
