From 81ae67a634d3bd72b10f798490ee25c3a3cb807a Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Tue, 8 Nov 2016 15:04:30 -0600 Subject: Add Haswell Chromeboxes/Chromebase using variant board scheme Combine existing board google/panther with new ChromeOS devices mccloud, monroe, tricky, and zako, using their common reference board (beltino) as a base. Chromium sources used: firmware-mccloud-5827.B 65bfee7 [haswell: No need pre-graphics delay...] firmware-monroe-4921.B 1ac749d [Monroe: Disable KB/MS in ITE8772.] firmware-tricky-5829.B 2db5322 [haswell: No need pre-graphics delay...] firmware-zako-5219.B eacedef [haswell: No need pre-graphics delay...] Existing google/panther board will be removed in a subsequent commit.
