Subject: [PATCH edk2-platforms v2 15/18] ARM/VExpressPkg: New DP500/DP550/DP650 platform library.
Date: Fri, 22 Dec 2017 19:08:18 +0000 [thread overview]
Message-ID: <20171222190821.12440-16-evan.lloyd@arm.com> (raw)
In-Reply-To: <20171222190821.12440-1-evan.lloyd@arm.com>
From: Girish Pathak <girish.pathak at arm.com>
This change adds LcdPlatformLib implementation for ARM Mali
DP500/DP500/DP650 display processors for models (with DP550 support).
NOTE: Versions for actual hardware are liable to require extra handling
for clock input changes, etc.
