Subject: [staging/cadence-aarch64 PATCH v3 3/6] CadencePkg: Add PCI host bridge library for Cadence PCIe Root Complex.
Date: Thu, 22 Jun 2017 10:31:58 +0100	[thread overview]
Message-ID: <1498123921-4638-4-git-send-email-stelford@cadence.com> (raw)
In-Reply-To: <1498123921-4638-1-git-send-email-stelford@cadence.com>

Add PciHostBridgeLib implementation for the Cadence PCIe Root Complex.
This library is derived from
Platforms/ARM/Juno/Library/JunoPciHostBridgeLib in OpenPlatformPkg.
