I noticed one difference between your system and mine: U-Boot version.
On my system, it has rather old version now:

  Marvell>> version
  U-Boot 2017.03-armada-17.10.2-g14aeedc (Jun 01 2018 - 15:39:10 +0800)
  aarch64-linux-gnu-gcc (Linaro GCC 5.2-2015.11-2) 5.2.1 20151005
  GNU ld (GNU Binutils) 2.25.0 Linaro 2015_10

Do you think it's worth trying the latest U-boot?

Yes, please update firmwares to the latests versions. Or at least try to
boot new U-Boot via UART (without replacing existing version) and check
for differences.

Building documentations:
https://trustedfirmware-a.readthedocs.io/en/latest/plat/marvell/armada/build.html
https://source.denx.de/u-boot/u-boot/-/blob/v2022.07/doc/README.marvell

UART booting documentation is currently waiting for review:
https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/16198

Thanks for the good references. I've managed to build U-Boot for UART booting (I
use fedora, then needed to identify Fedora packages corresponding to guided apt
packages. I also needed to fix a build failure in A3700-utils-marvell.)

I modified board jumper pins to UART mode and downloaded the built U-Boot using
mox-imager. The downloaded U-Boot showed the new version and detected my SSD:

  => version
  U-Boot 2022.10-rc2-00049-g157861e6af (Aug 12 2022 - 18:10:21 +0900)

  aarch64-linux-gnu-gcc (GCC) 12.1.1 20220507 (Red Hat Cross 12.1.1-1)
  GNU ld version 2.37-7.fc36
  => scsi scan
  scanning bus for devices...
    Device 0: (0:0) Vendor: ATA Prod.: SanDisk SDSSDA24 Rev: U210
              Type: Hard Disk
              Capacity: 228936.5 MB = 223.5 GB (468862128 x 512)

However, after booting Linux kernel v5.18.16 from the U-Boot, still the error
message "ata1: SATA link down (SStatus 0 SControl 300)" is printed.
This may indicate that the error is not related U-Boot.

Now I'm not sure what's the key difference between your system and mine. If
there is anything I can do next, please let me know.

Probably this is SSD disk specific. I will try to prepare some kernel
changes to test if it changes something.
