If U-Boot is not the first-stage bootloader we should not init the keyboard, since it has already been done. Check for this.
But re-init does no harm, right?
Actually it causes the keyboard to fail on Brya (Felwinter), a Chromebook. It could be due to it having a numeric keypad.
I assume Linux kernel will do the keyboard re-init no matter what bootloader does. So does Linux kernel fail to re-init the keyboard? If no, I guess we could improve the U-Boot keyboard driver somehow?
