cmd: fru: Move fru_data to data section instead of bss section
I didn't fully check it but I think that there is an issue to use FIT
images with dtb again when bss section is cleared. U-Boot copy just
origin DTB and if embedded_dtb_select() doesn't find new DTB then can't
go back to origin DTB file.
Move this structure to data section for now.
It should be allocated by malloc anyway.

This patch adds support for fru commands "fru capture"
and "fru display". The fru capture parses the FRU table
present at an address and stores in a structure for later
use. The fru display prints the content of captured structured
in a readable format.
As of now, it supports only common header and board area of FRU.
Also, its supports only English language code and ASCII8 format.

arm64: zynqmp: add tool to convert PMU config object .c to binary
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

Add a simple Python script to do the conversion.
It is definitely not a complete C language parser, but it is enough to

- defines

- bitwise OR between them

arm64: zynqmp: spl: install a PMU firmware config object at runtime
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:

they depend on. Currently not all PL IP drivers are CCF compliant and some

IPs/Drivers that are not CCF compliant. So, keep all PL clocks always
enabled by enabling fclk nodes.
For cases which require active PL clock management, it should first be
