10 On Zynq and ZynqMP U-Boot SPL (or U-Boot proper if
11 ZYNQMP_PSU_INIT_ENABLED is set) is responsible for some
12 basic initializations, such as enabling peripherals and
13 configuring pinmuxes. The PS init file (called
14 psu_init_gpl.c on ZynqMP, ps7_init_gpl.c for Zynq-7000)
15 contains the code for such initializations.
17 U-Boot contains PS init files for some boards, but each of
18 them describes only one specific configuration. Users of a
19 different board, or needing a different configuration, can
20 generate custom files using the Xilinx development tools.
22 There are three ways to give a PS init file to U-Boot:
24 1. Set this variable to the path, either relative to the
25 source tree or absolute, where the psu_init_gpl.c or
26 ps7_init_gpl.c file is located. U-Boot will build this
29 2. If you leave an empty string here, U-Boot will use
30 board/xilinx/zynq/$(CONFIG_DEFAULT_DEVICE_TREE)/ps7_init_gpl.c
32 board/xilinx/zynqmp/$(CONFIG_DEFAULT_DEVICE_TREE)/psu_init_gpl.c
35 3. If the above file does not exist, U-Boot will use
36 board/xilinx/zynq/ps7_init_gpl.c for Zynq-7000, or
37 board/xilinx/zynqmp/psu_init_gpl.c for ZynqMP. This file
38 is not provided by U-Boot, you have to copy it there
