Subject: [PATCH v2 0/2] pci: xgene: Add multiple memory ranges support
Date: Tue, 30 Jun 2015 11:22:26 -0700 [thread overview]
Message-ID: <cover.1435688121.git.dhdang@apm.com> (raw)
In-Reply-To: <46305464.n5SOjGAhJb@wuerfel>
This patch set adds 1 large (up to 64GB) memory window for each PCIe
controller nodes in X-Gene device tree and fix PCIe controller driver
to handle multiple memory ranges correctly. These changes are required
to support PCIe devices that has huge BAR.
v2 changes:
1. Separate device-tree changes and driver changes into different
patches
2. Explicitly define new large window as 64-bit prefetchable in dts
3. Use IORESOURCE_PREFETCH flag to determine which PCIe controller
register to be used to configure the memory ranges.
