The PS init file (called + psu_init_gpl.c on ZynqMP, ps7_init_gpl.c for Zynq-7000) + contains the code for such initializations. + + U-Boot contains PS init files for some boards, but each of + them describes only one specific configuration. Users of a + different board, or needing a different configuration, can + generate custom files using the Xilinx development tools. + + There are three ways to give a PS init file to U-Boot: + + 1.
