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