Looks rather like a TF-A path to me, CC'ing Varun. As Yousaf says above, it's the TF-A you guys ship with latest R32.1.0. Maybe the tftpboot operation is overwriting memory used by your TF-A, or differing memory usage is uncovering a missing U-Boot EFI reservation? (I recently wondered whether TX1 may be missing some, as I needed multiple tries to boot the kernel successfully there - TF-A 2.1 didn't work there, so some more investigations TBD. R28.3.0 still wasn't booting U-Boot ~2019.04, I needed R24.2.2 still as you once suggested.)
