Theoretically, yes. Practically, it would be a *LOT* of work and
require hardware details that you probably cannot get (chipset register
definitions, how to initialize them, etc.).
With GRUB, the manufacturer's BIOS initialize the chipset and then boots
GRUB -> linux based on the already configured hardware. U-Boot
initializes the hardware, so you need the information that the PC BIOS /
hardware manufacturer has (and won't tell you) to replace BIOS+GRUB with
U-Boot.
There is some support for x86 in u-boot, but it is for one (?) specific
x86 CPU, the AMD sc520, and your PC probably isn't running that.

That is a huge open-ended question. We don't have an answer.

You probably don't have a sc520.

Use the BIOS + GRUB. It works very well.
