From 87f265b210e02a7aefb6da0bae61c2b0d9239a3e Mon Sep 17 00:00:00 2001 From: Nicolas Boichat Date: Tue, 6 Aug 2019 08:29:52 +0800 Subject: lib/edid: Add suport for display rotation Sometimes the display native orientation does not match the device default orientation. We add a parameter to be passed to libpayload, which can then do the rotation. BUG=b:132049716 TEST=Boot krane, see that FW screen is orientation properly.
