[U-Boot] [U-boot] Does u-boot.bin only include a data section?

Hi, experts:

I am studying u-boo.bin format(which is got from u-boot, an ELF format bin).

I run the below command:

Objdump -h -b binary -m arm u-boot.bin

Found only a .data section was displayed.

So , does u-boot.bin include only a .data section?

Best wishes,
