Can’t boot FIT kernel image

[Алексей Беляев]

Hello!

I'm trying to make FIT Kernel+dtb image for U-Boot.
```
mkimage -E -f Image.its Image.new
```

Image.its:
```
/dts-v1/;

/ {
         description = "ARM64 OpenWrt FIT (Flattened Image Tree)";
         #address-cells = <1>;

         images {
                 kernel at 1 {
                         description = "ARM64 OpenWrt Linux-5.4.60";
                         data = /incbin/("arch/arm64/boot/Image.lzma");
                         type = "kernel";
                         arch = "arm64";
                         os = "linux";
                         compression = "lzma";
                         load = <0x40008000>;
                         entry = <0x40008000>;
                         hash at 1 {
                                 algo = "crc32";
                         };
                         hash at 2 {
                                 algo = "sha1";
                         };
                 };

                 fdt at 1 {
                         description = "ARM64 OpenWrt 
xunlong_orangepi-zero-plus2 device tree blob";
                         data = 
/incbin/("sun50i-h5-orangepi-zero-plus2.dtb");
                         type = "flat_dt";
                         arch = "arm64";
                         compression = "none";
                         load = <0x4FA00000>;
                         hash at 1 {
                                 algo = "crc32";
                         };
                         hash at 2 {
                                 algo = "sha1";
                         };
                 };

         };

         configurations {
                 default = "config at 1";
                 config at 1 {
                         description = "OpenWRT";
                         kernel = "kernel at 1";
                         fdt = "fdt at 1";
                 };
         };
};
```

and it Look like good. U-boot print correct Information about it.

And device has freeze.

Kernel and dtb is fine. I have Image.lzma and "dtb" files distinctly and 
their work fine:

What I do wrong?

PS. Kernel boot normally by next command:
```
lzmadec 0x53e0043c 0x40008000
imxtract 53e00000 fdt at 1 0x4FA00000
booti 0x40008000 - 0x4FA00000
```
