google/eve: Enable keyboard backlight in bootblock
Enable the keyboard backlight as early in boot as possible to provide a indication that the BIOS is executing. Since this is bootblock it can't use the convenience function for checking for S3 resume so just read the PM1 value from the SOC and check it directly. Use a value of 75% for the current system as that is visible without being full brightness. BUG=chrome-os-partner:61464 TEST=boot on eve and check that keyboard backlight is enabled as soon as the SOC starts booting Change-Id: I9ac78e9c3913a2776943088f35142afe3ffef056 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/18197 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net>
