	  Location of a PMU firmware binary.

	  If not empty, instructs the U-Boot build process to generate
	  a boot.bin (to be loaded by the ZynqMP boot ROM) containing
	  both the U-Boot SPL and the PMU firmware in the
	  Xilinx-specific boot format.

	  The value can be an absolute or relative path, and will be
	  used directly from where it is located, or an URI
	  (e.g. http://...), and it will be downloaded and used from
	  the download directory.

	  The PMU firmware binary can be either in ELF or BIN format.

	  If empty, the generated boot.bin will not contain a PMU
	  firmware.

	  This feature requires U-Boot >= 2018.07.

config BR2_TARGET_UBOOT_ZYNQMP_PM_CFG
	string "PMU configuration location"
	depends on BR2_TARGET_UBOOT_BUILD_SYSTEM_KCONFIG
	help
	  Location of a PMU configuration file.

	  If not empty, Buildroot will convert the PMU configuration
	  file into a loadable blob and pass it to U-Boot. The blob gets
	  embedded into the U-Boot SPL and is used to configure the PMU
	  during board initialization.

	  Unlike the PMU firmware, the PMU configuration file is unique
	  to each board configuration. A PMU configuration file can be
	  generated by building your Xilinx SDK BSP. It can be found in
	  the BSP source, for example at
	    ./psu_cortexa53_0/libsrc/xilpm_v2_4/src/pm_cfg_obj.c

	  Leave this option empty if your PMU firmware has a hard-coded
	  configuration object or you are loading it by any other means.

	  This feature requires U-Boot >= v2019.10.

	  On ZynqMP the bootloader is responsible for some basic
	  initializations, such as enabling peripherals and
	  configuring pinmuxes. The psu_init_gpl.c file (and,
	  optionally, psu_init_gpl.h) contains the code for such
	  initializations.

	  Although U-Boot contains psu_init_gpl.c files for some
	  boards, 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.

	  Set this variable to the path to your psu_init_gpl.c file
	  (e.g. "board/myboard/psu_init_gpl.c"). psu_init_gpl.h, if
	  needed, should be in the same directory. U-Boot will build
	  and link the user-provided file instead of the built-in one.

	  Leave empty to use the files provided by U-Boot.

	  This feature requires commit
	  6da4f67ad09cd8b311d77b2b04e557b7ef65b56c from upstream

	  Pass the U-Boot image through the mkpimage tool to enable
	  booting on the Altera SoC FPGA based platforms.

	  On some platforms, it's the SPL that needs to be passed
	  through mkpimage. On some other platforms there is no SPL
	  because the internal SRAM is big enough to store the full
	  U-Boot. In this case, it's directly the full U-Boot image
	  that is passed through mkpimage.

	  If BR2_TARGET_UBOOT_SPL is enabled then
	  BR2_TARGET_UBOOT_SPL_NAME is converted by mkpimage using
	  header version 0.

	  Otherwise the full u-boot-dtb.bin is converted using
	  mkpimage header version 1.

	  In either case the resulting file will be given a .crc
	  extension.
