Subject: [PATCH v2 4/5] arm64: Juno: Add support for the PCIe host bridge on Juno R1
Date: Fri, 9 Oct 2015 17:57:28 +0100 [thread overview]
Message-ID: <1444409849-5685-5-git-send-email-Liviu.Dudau@arm.com> (raw)
In-Reply-To: <1444409849-5685-1-git-send-email-Liviu.Dudau@arm.com>
Juno R1 board sports a functional PCIe host bridge that is
compliant with the SBSA standard found [1] here. With the right
firmware that initialises the XpressRICH3 controller one can
use the generic Host Bridge driver to use the PCIe hardware.
