Doing so with U-Boot 2025.01 compiled for qemu_arm64_defconfig currently leads to a crash when accessing the PL061 GPIO controller device for identification. It seems that U-Boot (or TF-A, which wasn't included in my setup) should have done some initial setup to allow access to the PL061. barebox doesn't even have a driver for the peripheral and loading barebox directly with -kernel works. In both cases, barebox runs in EL1. Let's thus workaround the issue on the barebox side by using the new CONFIG_ARM_AMBA_DABT_MASK option to turn the crash into an error message.
