Why would I want to address memory in RM with 32 Bits? I don't see any difference to using PM without Paging enabled.
In a bootloader (after coreboot) you often want to call BIOS interrupt services which assume real mode, because that was the only mode, when the interrupt services were created.
For coreboot itself, I think there is little if any advantage to big real mode.
