Change in ...coreboot[master]: libpayload/drivers/i8042: ignore special keys on keyboard

( https://review.coreboot.org/c/coreboot/+/33303 Change subject: libpayload/drivers/i8042: ignore special keys on keyboard ...................................................................... libpayload/drivers/i8042: ignore special keys on keyboard Some keyboards have a fn-key (and/or fn-mode lock) that can generate 0xe0-prefixed scan codes for certain keys. Previously the 0xe0 prefix state wasn't tracked (it was ignored), so these scan codes could be misinterpreted as non-0xe0 presses (e.g., 'mute' generates 0xe0 0x20 but this would get interpreted as 0x20 and be treated as a 'D' press). Most 0xe0-prefixed codes (besides those for the 10-key) are irrelevant for firmware so we'll ignore them. BUG=none BRANCH=none TEST=local build and flash.
