Subject: [PATCH 06/14] powerpc/85xx: Cleanup PCIe support on corenet_ds boards
Date: Fri, 20 May 2011 01:09:23 -0500	[thread overview]
Message-ID: <1305871771-16334-6-git-send-email-galak@kernel.crashing.org> (raw)
In-Reply-To: <1305871771-16334-5-git-send-email-galak@kernel.crashing.org>

Several changes on PCIe support on P3041DS/P4080DS/P5020DS boards:
* Add support for "fsl,qoriq-pcie-v2.2" needed by P3041 & P5020
* Removed support for setting primary_phb_addr as we have no ISA need
* Add PCI controller to of_platform_bus_probe (for EDAC)
* Cleanup building w/SWIOTLB off on P4080DS (not stricly PCIe related)
