google/storm: use whirlwind LED ring on SP5 boards
The latest whirlwind requirements call for the need to indicate different device states while it is still in coreboot (it could be waiting for recovery or for factory reset trigger). Initialize the LED ring when running on the SP5 hardware (which is the first proper Whirlwind device). BRANCH=storm BUG=chrome-os-partner:36059 TEST=when the device starts the LED ring gets shut down Change-Id: I9dd0bca4849a2a8500322c84c7351aeef00d862e Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Original-Commit-Id: 24e4da56d4c43d03f235d0cfd5995ef235e6a2c5 Original-Change-Id: Ica37301aa27f35897d2bf467ae319fb5e68adc1d Original-Signed-off-by: Vadim Bendebury <vbendeb@chromium.org> Original-Reviewed-on: https://chromium-review.googlesource.com/258271 Original-Reviewed-by: David Hendricks <dhendrix@chromium.org> Reviewed-on: http://review.coreboot.org/9859 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
