This replaces various timing mode parameters parameters with an edid_mode struct within the edid struct. BUG=none BRANCH=firmware-veyron TEST=built and booted on Mickey, saw display come up, also compiled for link,falco,peppy,rambi,nyan_big,rush,smaug [pg: extended to also cover peach_pit, daisy and lenovo/t530] Change-Id: Icd0d67bfd3c422be087976261806b9525b2b9c7e Signed-off-by: Patrick Georgi <patrick@georgi-clan.de> Original-Commit-Id: abcbf25c81b25fadf71cae106e01b3e36391f5e9 Original-Change-Id: I1bfba5b06a708d042286db56b37f67302f61fff6 Original-Signed-off-by: David Hendricks <dhendrix@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/289964 Original-Reviewed-by: Yakir Yang <ykk@rock-chips.com> Original-Reviewed-by: Julius Werner <jwerner@chromium.org> Reviewed-on: http://review.coreboot.org/11388 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
