- On Zynq and ZynqMP U-Boot SPL (or U-Boot proper if
- ZYNQMP_PSU_INIT_ENABLED is set) is responsible for some
- basic initializations, such as enabling peripherals and
- configuring pinmuxes. 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. Set this variable to the path, either relative to the
- source tree or absolute, where the psu_init_gpl.c or
- ps7_init_gpl.c file is located. U-Boot will build this
- file.
- 2. If you leave an empty string here, U-Boot will use
- board/xilinx/zynq/$(CONFIG_DEFAULT_DEVICE_TREE)/ps7_init_gpl.c
- for Zynq-7000, or
- board/xilinx/zynqmp/$(CONFIG_DEFAULT_DEVICE_TREE)/psu_init_gpl.c
- for ZynqMP.
- 3. If the above file does not exist, U-Boot will use
- board/xilinx/zynq/ps7_init_gpl.c for Zynq-7000, or
- board/xilinx/zynqmp/psu_init_gpl.c for ZynqMP. This file
- is not provided by U-Boot, you have to copy it there
- before the build.
