I'm not quite sure where the problem is, next. After enabling FIT image
support in my build so I can use the image I have on hand:
U-Boot> tftpboot 200000 v6.6/image.fit.nocomp
Waiting for Ethernet connection... done.
Using smsc95xx_eth device
TFTP from server 192.168.1.10; our IP address is 192.168.1.100
Filename 'v6.6/image.fit.nocomp'.
Load address: 0x200000
Loading: ##################################################  82 MiB
         3.2 MiB/s
done
Bytes transferred = 85984256 (5200400 hex)
U-Boot> U-Boot> crc32 200000 $filesize
CRC32 for 00200000 ... 054003ff ==> 754c839a
U-Boot> U-Boot> bootm 200000
## Loading kernel from FIT Image at 00200000 ...
Could not find configuration node
ERROR -2: can't get kernel image!
U-Boot>

And in u_boot_boardenv_rpi_arm64.py:
env__tftp_boot_test_skip = False

env__net_tftp_bootable_file = {
    'fn': 'v6.6/image.fit.nocomp',
    'addr': 0x00200000,
    'size': 85984256,
    'crc32': '754c839a',
    'pattern': 'Linux',
    'config': 'conf-852',
}

But it's not trying to boot conf-852 but instead just passing the
address. This image lacks a default config, which your example has and I
think is why the tests work in your case.
