+qemu-system-aarch64 -M raspi4b -- no valid DTB provided in x0 register
+Description of problem:
+When starting `qemu-system-aarch64 -M raspi4b`, no valid DTB is provided in x0.
+Steps to reproduce:
+Make a simple binary to loop forever
+
+```
+$ cat loop.c
+void _start(void)
+{
+	for(;;)
+		;
+}
+$ aarch64-linux-gnu-gcc loop.c -nostdlib
+$ aarch64-linux-gnu-objcopy -O binary a.out loop.bin
+```
+
+Start qemu for debugging and start gdb
+
+```
+$ qemu-system-aarch64 -S -s -M raspi4b -kernel loop.bin
+# in another terminal
+$ aarch64-linux-gnu-gdb
+(gdb) target remote :1234
+Remote debugging using :1234
+warning: No executable has been specified and target does not support
+determining executable automatically.  Try using the "file" command.

+Note that at no time is a valid DTB provided in x0. I expected to see the DTB magic 0xd00dfeed (or 0xedfe0dd0) at the memory pointed to by x0
