Enable DFU tftp support for firmware update. Fill dfu_ram_tftp variable to have command present for showing how to use it.

boot FIT image has been created from below fragment. Key part is that type of image has to be firmware. Also based on experiment load property is completely ignored and base addresses are taken from dfu_alt_info variable.

$ cat update_uboot.its /dts-v1/;

/ { description = "Automatic U-Boot update"; #address-cells = <1>;

images { Image { description = "Kernel"; data = /incbin/("/tftpboot/Image"); compression = "none"; arch = "arm64"; type = "firmware"; os = "linux"; load = <0x80000>; entry = <0x80000>; hash-1 { algo = "sha1"; }; }; system.dtb { description = "DTB"; data = /incbin/("/tftpboot/system.dtb"); compression = "none"; arch = "arm64"; type = "firmware"; load = <0>; hash-1 { algo = "sha1"; }; }; }; };

$ mkimage -f update_uboot.its /tftpboot/boot

When U-Boot starts get IP address and server IP. dhcp setenv serverip 192.168.0.105

And then run prepared command. run dfu_ram_tftp

Image should be loaded to 0x80000 address and not to $kernel_addr_r. Also kernel_addr, fdt_addr and fdt_size in zynqmp case are not defined that's why define it to be aligned with Versal.
