I 
have tried it now with the Cortex-A57 but running into the same
issue without OP-TEE and TF-A. Using OP-TEE and TF-A works now
without the issue because I have forgotten to pass the option
TRANSFER_LIST=1 to TF-A and CFG_TRANSFER_LIST=y and
CFG_MAP_EXT_DT_SECURE=y to OP-TEE.

Host OS: Debian 13 (Trixie)
QEMU version:
$ qemu-system-aarch64 --version
QEMU emulator version 10.0.7 (Debian 1:10.0.7+ds-0+deb13u1+b1)

BTW: doc/board/emulation/qemu-arm.rst doesn't mention how to build
U-Boot with OP-TEE and TF-A. Should I include the build steps into the
docs and create a patch for the doc? I think it's also useful for
other users.

Kind regards,
