You do not need hardware debugger, nor any "real hardware". You can run
U-Boot in qemu-system and use qemu-system capabilities (-S -s) to export
remote gdb control via network TCP socket. Then you can attach your
local gdb to qemu-system (target remote localhost:1234) and debug qemu.

I have used this qemu-system feature more times as it is easier to debug
some issues directly on computer without need to use external HW. But
with ability to run "real u-boot.bin" binary like on read HW.
