Subject: [edk2-platform][PATCH v1 1/1] Platforms/RaspberryPi: Fix incorrect display resolution
Date: Tue, 29 Sep 2020 13:48:30 -0400 [thread overview]
Message-ID: <20200929174830.4955-1-Samer.El-Haj-Mahmoud@arm.com> (raw)
Fix https://github.com/pftf/RPi4/issues/100 by swapping RPi DisplayDxe
resolution settings for 640x480 and 800x600, which were incorrectly
mapped to the settings shown in the Setup configuration variable.
