Yes we are also booting every platform with EFI.  And tbh it's not only a
matter of distros that already use it.  Arm itself has the SystemReady
specification [1] which mandates the use of EFI in most of it's flavors (SR,
ES and IR). Keeping in mind U-Boot's EFI support is very close to be 100%
compliant,  I think it's beneficial overall to have pre-canned board configs
that support that.
