453bb77d09 arm64: xilinx: Never touch DDR if system has no DDR
If DDR is not mapped do not touch it. Default
XILINX_OF_BOARD_DTB_ADDR is pointing to DDR.

14ca9f7f5a dm: core: Rename ofnode_get_chosen_prop()
This function is actually intended to read a string rather than a
property. All of its current callers use it that way. Also there is no way
to return the length of the property from this function.

Rename it to better indicate its purpose, using ofnode_read as the prefix
since this matches most other functions.

Also add some tests which are missing for these functions.

fc274a5932 arm64: zynqmp: Add support for OF_SEPARATE with board DTB
OF_BOARD and OF_SEPARATE can use board specific board_fdt_blob_setup().

OF_BOARD option is mostly used for picking up DTB from certain location.

OF_SEPARATE option is used when DTB is appended after u-boot binary.

This board specific function is aligned with current version in
lib/fdtdec.c with checking CONFIG_XILINX_OF_BOARD_DTB_ADDR address first.

db5b253f01 arm64: zynqmp: Rename fw_dtb variable to fdt_blob
The reason for this change is just get in sync with board_fdt_blob_setup()
available at lib/fdtdec.c.

f4e7e61193 arm64: xilinx: Enable generic of_board_dtb
Modify the configuration naming to be generic to xilinx rather than
specific to Versal. The offset value is different for Zynq and ZynqMP
to avoid overlapping with FSBL.

027b1134b2 xilinx: common: Remove !DM_i2C code for reading mac from eeprom
All platforms are converted to DM_I2C that's why there is no reason to
keep this code here.

829e8c73dd xilinx: common: Add support for DM_I2C zynq_board_read_rom_ethaddr()
It is much easier to point to eeprom which stores information like MAC
address directly via DT. eeprom which contains this information is
pointed by /chosen/xlnx,eeprom parameter.

For example:
        chosen {
                bootargs = "earlycon";
                stdout-path = "serial0:115200n8";
+               xlnx,eeprom = &eeprom;
        };

9755e3db8b xilinx: Move zynq_board_read_rom_ethaddr to shared location
Zynq and ZynqMP are sharing similar code and there is no reason to do
code duplication. Move zynq_board_read_rom_ethaddr() to common file for
easier conversion to DM.
Use ZynqMP version that's why also add CONFIG_ZYNQ_EEPROM_BUS to Syzygy
which is only one Zynq board which is using this feature.
