it also detects no-mode and +assumes mode 1, on really old keyboards. + +The current behaviour has been retained, for everything +except GRUB_MACHINE_COREBOOT; for the latter, scan code +set 2 with translation is hardcoded, and forced in code. + +This is required to make keyboard initialisation work on +the MEC5035 EC used by the Dell Latitude E6400, when +running GRUB as a coreboot payload on that laptop. The +EC reports scancode set 2 with translation when probed, +but actually only outputs scancode set 1. + +Since GRUB is attempting to use it without translation, +and since the machine reports set 2 with translation, +but only ever outputs set 1 scancodes, this results in +wrong keypresses for every key. + +This fix fixed that, by forcing set 2 with translation, +treating it as set 1, but only on coreboot. This is the +same behaviour used in GNU+Linux systems and SeaBIOS. +With this change, GRUB keyboard initialisation now works +just fine on those machines. + +This has *also* been tested on other coreboot machines +running GRUB; several HP EliteBooks, ThinkPads and +Dell Precision T1650.
