The LXA boards are the only upstream STM32 boards that set stdout-path = &uart* instead of explicitly specifying a baud rate.
This would mean the default of 9600 is used, but it goes unnoticed when booting normally as barebox fixes up a console= line that includes a baud rate. When EFI booting GRUB however, GRUB will not pass along the console= line and thus the board ends up with a 9600 baud Linux console, confusing users. A fix for this has been submitted upstream[1]. Until then, have the fix in barebox as barebox will pass along its device tree when booting via EFI.
