d388cedd46 xilinx: Add DDR base address to bootscript address
Add ram base address to scriptaddr env variable to make boot
script address to be a valid address when ddr base address changes.

This works properly if the first memory region is the region where uboot
runs. Also the solution was taken in respect of a lot of jtag script
putting u-boot script to certain address. For standard cases
bd->bi_dram[0].start is 0 all the time. Only for systems with DDR placed
out of this location it does calculation.

This is not the best solution and should be done differently in future but
enough for now till we don't have full solution ready yet.

d93fbac512 arm64: zynqmp: Fix zynqmp mini qspi max frequency
For zynqmp qspi, frequencies up to 40MHz will work irrespective
of feedback clock enabled or disabled. If we want higher than
40Mhz the feedback clock should be enabled.

With spi-max-frequency 108MHz it is not working when the feedback
clock is disabled. Change it to 40MHz so that it works irrespective
of feedback clock enabled or disabled.

07499daf50 xilinx: zynqmp: Do not check 0 as invalid return from snprintf
U-Boot SPL on ZynqMP is using CONFIG_SPL_USE_TINY_PRINTF which doesn't
return any return value and all the time returns 0. That's why
even correct snprintf was returning in SPL chip ID as "unknown".
Change checking condition and allow snprintf to return 0 which is according
manual patch successful return.
"If an output error is encountered, a negative value is returned."

4489e0aa9b xilinx: cmd: Add basic fru format generator
Idea is to have something what can be used for board bringup from
generic board perspective.

There is a violation compare to spec that FRU ID is ASCII8 instead of
binary format but this is really for having something to pass boot and
boot to OS which has better generating options.
Also time should be filled properly.

For example:
fru board_gen 1000 XILINX versal-x-prc-01-revA serialX partX

f1b97b5f18 xilinx: cmd: Add support for FRU commands
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, it
supports only English language code and ASCII8/BINARY formats.

fru_data variable is placed to data section because fru parser can be
called very early before bss is initialized. And also information needs to
be shared that's why it is exported via header.

caa7fc2c57 spl: Use standard FIT entries
SPL is creating fit-images DT node when loadables are recorded in selected
configuration. Entries which are created are using entry-point and
load-addr property names. But there shouldn't be a need to use non standard
properties because entry/load are standard FIT properties. But using
standard FIT properties enables option to use generic FIT functions to
descrease SPL size. Here is result for ZynqMP virt configuration:
xilinx_zynqmp_virt: spl/u-boot-spl:all -82 spl/u-boot-spl:rodata -22 spl/u-boot-spl:text -60

The patch causes change in run time fit image record.
Before:
fit-images {
        uboot {
                os = "u-boot";
                type = "firmware";
                size = <0xfd520>;
                entry-point = <0x8000000>;
                load-addr = <0x8000000>;
        };
};

After:
fit-images {
        uboot {
                os = "u-boot";
                type = "firmware";
                size = <0xfd520>;
                entry = <0x8000000>;
                load = <0x8000000>;
        };
};

Replacing calling fdt_getprop_u32() by fit_image_get_entry/load() also
enables support for reading entry/load properties recorded in 64bit format.

SPL also has an option to remove some DT properties which are useless for
SPL to make DT even smaller.
Default DT properties are pinctrl-0 pinctrl-names interrupt-parent
interrupts which are already removed.

f5d8b1a1f9 microblaze: start.S: Use board_init_f_alloc/init in early init
Implement early init by calling generic board_init_f_alloc_reserve and
board_init_f_init_reserve functions:
* drop SYS_MALLOC_F_LEN related code, as allocation and gd->malloc_base
  assignment are taken care of by the generic functions
* drop _gd logic
