For OpenSTLinux, two U-Boot files are used by ST boards to generate the FIP file used by FSBL TF-A, with or without OP-TEE support:
BL33_CFG=u-boot.dtb : the U-Boot device tree, selected by DEVICE_TREE, loaded by TF-A BL2 and amended by secure monitor (SP-MIN or OP-TEE)
BL33=u-boot-nodtb.bin: the U-Boot executable, loaded by TF-A BL2 started by secure monitor with BL33_CFG as parameter
Nota: All the compiled device tree are available in $KBUILD_OUTPUT/arch/arm/dts/*.dtb.
You can select them as BL33_CFG parameter without U-Boot recompilation.
See TF-A_overview for FIP details.
The file used to debug with gdb is
u-boot : elf file for U-Boot
The file u-boot.stm32, i.e. the U-Boot binary with STM32 header, is no more generated and used in OpenSTlinux.
