This change also causes issues on a kontron-sl-mx8mm and imx8mn ddr3 evk boards.

The problem on these boards is that serial console garbage is seen:

Net:   eth0: ethernet at 30be0000
Hit any key to stop autoboot:  0
u-boot=> [25;88R
Unknown command '[25' - try 'help'
Unknown command '88R' - try 'help'

These extraneous characters stop the boot process.

As a workaround, I disabled CONFIG_EFI_LOADER, and then the serial
garbage does not happen and the board can boot normally.

Heiko confirmed the same behavior on an imx8mn evk ddr3 board.
