Optionally allow U-Boot to load a configuration object into the Power Management Unit (PMU) firmware on Xilinx ZynqMP.

The configuration object is required by the PMU FW to enable most SoC peripherals. So far the only way to boot using U-Boot SPL was to hard-code the configuration object in the PMU firmware. Allow a different boot process, where the PMU FW is equal for any ZynqMP chip and its configuration is passed at runtime by U-Boot SPL.

All the code for Inter-processor communication with the PMU is isolated in a new file (pmu_ipc.c). The code is inspired by the same feature as implemented in the Xilinx First Stage Bootloader (FSBL) and Arm Trusted Firmware:

• https://github.com/ARM-software/arm-trusted-firmware/blob/c48d02bade88b07fa7...

SPL logs on the console before loading the configuration object:

Changes v3 -> v4:

• fix pointer-to-integer typecast warning
• fix integer-to-pointer typecast warning with proper typecasting and add parentheses to avoid ambiguity
• fix kerneldoc syntax (Michal)
• remove empty line in Kconfig (Michal)
• remove #ifdefs around function declaration (Michal)
• remove unneeded file copy (Michal)
• move externs to a new .h file (Michal)
• avoid passing the extra -DZYNQMP_LOAD_PM_CFG_OBJ (using sizeof(), it looks a bit of a hack but seems to be working)
• rename CONFIG_ZYNQMP_LOAD_PM_CFG_OBJ_FILE to CONFIG_ZYNQMP_SPL_PM_CFG_OBJ_FILE and clarify in menuconfig that it's SPL-related

Changes RFC v2 -> v3:

• don't compile pm_cfg_obj.c from source, load it from a binary file (suggested by Michal)
• move IPC code to arch/arm/mach-zynqmp/ and sys_proto.h (Michal)

Changes RFC v1 -> RFC v2:

• Load the cfg_obj in SPL, not U-Boot proper: this required a complete reimplementation since we cannot rely on ATF now
• Update and refine the Kconfig option help

The recently-added ZYNQMP_SPL_PM_CFG_OBJ_FILE option allows SPL to load a PMUFW configuration object from a binary blob. However the configuration object is produced by Xilinx proprietary tools as a C source file and no tool exists to easily convert it to a binary blob in an embedded Linux build system for U-Boot to use.

Add a simple Python script to do the conversion.

It is definitely not a complete C language parser, but it is enough to parse the known patterns generated by Xilinx tools, including:

• defines
• literal integers, optionally with a 'U' suffix
• bitwise OR between them

I think it would be good to remove this or apply patch below.
