[U-Boot] BIOS EMULATOR driver

Hello, I'm working on one project about bios emulator and I notice that this driver is linked for boards P1022DS and sequoia too, but they don't really use any methods of it. It's safe to remove this support from configs files? Whole this driver is seems to be imported from somewhere and lots of its code is unused Actually only one method is used. It's safe to clean this too?

Thanks for answer Viktor Krivak
