If needed to add PMIC customization in FSBL, then refer the functions ‘configure_ldo1()’ & ‘configure_ldo4()’ from the patch provided in the petalinux project.
Then these functions has to be called in the FSBL file ‘ps7_init.c’. Refer petalinux file ‘project-spec/meta-user/recipes-bsp/fsbl/fsbl_%.bbappend’ for adding function calls.
Now this FSBL can be used to configure PMIC and can be used with bare-metal application.
If not configuring the Serdes in Vivado, then these functions can be called in the same file in the function ‘psu_init’ after the line ‘init_peripheral()’.
