How to disable FIP when building TF-A ?

[ruanxingzhi]

 

Hi community,

I am attempting to compile TF-A in a straightforward manner, similar to ecosystem v2, which packs BL2 & BL32 to  only one single .stm32 file for writing to fsbl1/fsbl2.

However, FIP is enabled by default in ecosystem v5. I am curious about how to disable it?

 

Ecosystem v3 release note  mentioned that it can be done by setting MACHINE_FEATURES_remove = "fip", but I cannot find the config file.
