U-Boot SPL is currently unable to load a PMU FW config object AFAIK. The
current best hack to boot with U-Boot SPL is to let PMU FW load a
hard-coded cfg object. This is implemented in [0].

But you need a configuration object of course. You can obtain one by
generating an FSBL with Xilinx XSDK, it will be in a path similar to
fsbl_bsp/psu_cortexa53_0/libsrc/xilpm_v2_1/src/pm_cfg_obj.c
