From 512059118e9ff56d2b4f3c324db5e764e288ac68 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Fri, 17 Mar 2017 17:59:54 +0100 Subject: Handle Intel Wildcat Point *LP* like Lynx Point LP MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The subtle difference was ignored when adding these chipsets. The integrated Wildcat Point LP PCH is documented in [1]. I'm not sure how to account for "Broadwell H" which seems not publicly documented. Maybe it's an unreleased HM9*, in which case the non-LP path should be correct.
